Book excerpt: Among renewable fuels, hydrogen is an appealing energy carrier for mitigating climatechange arising from the anthropogenic emissions of CO2. Most hydrogen is currentlyproduced by steam reforming (SR) from fossil fuels. For specific applications, hydrogenyield/purity can be enhanced via the integration of steam reforming and sorptionintensification in a single step/reactor (SESR). However, the high and unceasingconsumption of fossil fuels results in the exhaustion of finite resources and negative effectson the environment. With a scenario of green-economic sustainable development, there is agrowing interest in the recycling and valorization of a variety of industrial wastes and residualmaterials to a broad spectrum of value-added products. In particular, hydrogen productionfrom renewable byproduct substrates is widely recognized and investigated as a promisingapproach to mitigate energy and environmental crises. The booming of biodiesel productionhas resulted in the increase of glycerol (C3H8O3), byproduct, which can represent however apotential feedstock candidate to be adopted in green technologies for conversion intohydrogen. On the other side, another industrial waste, coal fly ash (FA), is vastly generatedfrom coal combustion in thermal power plants. Due to its high thermal stability and the factthat it contains several metal oxides, FA can act as potential alternative solid support and/orpromotor for developing heterogeneous catalysts. The hydrogen production (SR and/or SESR)presents therefore opportunities to valorize glycerol and FA wastes in a green approach(GSR/SEGSR).In the context of the importance of turning wastes into value-added products, this thesis dealswith a combined valorization of two important industrial residues (namely, FA for developingefficient Ni-based catalysts (yNi-FAx) and bifunctional catalyst-sorbent materials (Ni-CaO-FA), and glycerol as potential alternative feedstock) for sustainable green hydrogenproduction by GSR and SEGSR processes. More specifically, the main objectives of our workwere 1) investigating the influence of FA types, Ni loading, and reforming temperature onthe catalytic performance of yNi-FAx catalysts, 2) proposing a novel method for improvingthe properties of raw FA by adjusting the physicochemical properties using acid/alkalitreatments, and 3) developing bifunctional Ni-CaO-FA catalyst-sorbent materials for multi-cyclic SEGSR/regeneration operation.(1) FA supported Ni catalysts (Ni-FA) were synthesized via solid-state impregnation method.The effect of different parameters including (i) types of FA, (ii) Ni loading (2.5 - 15 wt.%),and (iii) reforming temperature (530 - 730 °C) on the catalytic performance of yNi-FAxcatalysts over GSR was investigated. The best performance in terms of activity (glycerolconversion to gas = 98 %, hydrogen yield = 78.8 %) and stability (40 h, with a low rate ofcoke formation and sintering 2.44 mgcoke•g−1catalyst•h−1) was achieved for 7.5 wt.% Ni-FA4 catalyst at 630 °C. This performance was attributed to a higher dispersion of Ni° active sitesand stronger interaction with the support, due to the higher surface area of FA4 and theexistence of nepheline (providing vacancy sites for anchoring Ni particles) and thermostablemullite.(2) In light of the catalytic performance of Ni-FAx catalyst (1), simple acid/alkali treatmentswere carried out to improve a low-efficiency FA (as support of Ni-based catalyst) byregulating its properties via one-step (HNO3 or NaOH) or two-step (NaOH/HNO3 orHNO3/NaOH) leaching-partial-dissolution (LPD). The influence of the treatment sequenceon the activity of the developed catalysts was highlighted. The results show that the catalyticactivity of Ni-FA(treated) catalysts for GSR was significantly improved compared to theuntreated materials. Alkali-LPD is more effective than acid-LPD in both improving FA’ssurface area and adjusting FA’s elemental distribution. Ni-FA(HNO3/NaOH) has the bestperformance with glycerol conversion to gas of 99.2 % and hydrogen yield of 74.5 %,attributed to (i) the removal of sulfur-containing species via acid-LPD, (ii) improvement ofspecific surface area, iron exposure, and Ni dispersion via alkali-LPD, (iii) reduction of cokeformation by acid/alkali-LPD sequence treatment, and (iv) enhancement of catalytic stabilitydue to the formation of NiFe alloys. (3) To synthesize bifunctional catalyst-sorbent materials, an attempt was initially made tomodify a CaO-based sorbent by adding different types of FA (FAx (x = 1 to 12)) to develophighly efficient and economical CaO-based sorbents for CO2 removal at high temperatures.The results showed that CaO-FA5 (90 wt.% CaO) sorbent offered the most stable CO2 captureactivity over 20 cycles, with a CO2 capture capacity of 0.58 gCO2•gsorbent-1 at the 1st cycle and 0.45 gCO2•gsorbent-1 at the 20th cycle. This was attributed to the relatively high amounts of SiO2 and mullite (inert materials) in FA5 compared to the other FAx samples. The presence of these inert materials helps to enhance the sorbent stability by hindering their aggregation andsintering. This sorbent was then chosen to further synthesize a bifunctional catalyst-sorbentmaterial for highly pure hydrogen production via SEGSR. The Ni-CaO-FA5 bifunctionalmaterial exhibited a stable hydrogen purity of ~ 97 % and yield of ~ 90 % for 30 min (pre-breakthrough period). These results highlight the high potential of FA5 as a low-coststabilizer for improving the stability of CaO-based sorbents.In conclusion, through the valorization of both liquid (glycerol) and solid (coal fly ash)residual materials, the results presented in this thesis provide an economic and environmentalapproach to hydrogen production by GSR as well as the simultaneous CO2 capture and high-purity hydrogen production by SEGSR. Even though not all kinds of as-received (raw) FAmaterials are suitable for serving as catalytic support, simple acid/alkali treatments could leadto low-calcium/sulfur FA supports with superior physicochemical features. As for differentresidual liquid substrates, using solid wastes to catalytically produce hydrogen is anenvironmentally favorable and economically sustainable strategy. With the growing energycrisis, this aspect is becoming more important and pushing forward new attempts to convertmore wastes to value-added products

This book was released on 2019 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, hydrogen has attracted a great deal of attention as a green energy carrier. Currently, more than 95 % of hydrogen is produced from fossil fuels, which has been questioned by the depletion of resources andincrease of greenhouse gas emissions. Therefore, renewable, carbon-neutral resources such as biomass and biomass-derived chemicals has been receiving a growing interest as an option to produce hydrogen. As a main by product in the biodiesel manufacturing process, glycerol has emerged as a promising source for hydrogen production. Although steam reforming (SR) is being recognized as a promising approach for converting glycerol to hydrogen, this process faces a number of challenges including the presence of equilibrium-limited reactions and the need of an expensive downstream purification system. To alleviate these problems, a promising alternative is sorption enhanced steam reforming (SESR) process, in which steam reforming, water gas shift (WGS), and CO2 capture reactions occur simultaneously using areforming catalyst and a CO2solid sorbent. In this process, CO2 removal occurs simultaneously with the reforming reaction, shifting the WGS reaction towards hydrogen production and producing a hydrogen-enriched gas stream in a single step. The key factors in the successful application of this technology are mainly: (i) reforming catalysts and CO2 sorbents that can work efficiently under the harsh conditions of SESR process and (ii) mixing pattern of catalyst and sorbent. This thesis focuses on the development of efficient catalyst and catalyst-sorbent bifunctional materials for sustainable hydrogen production by SR and SESR of glycerol (SRG and SESRG). More specifically, four main objectives of our workare: (i) investigating the influence of steam addition during either carbonation or calcination on the CO2 capture performance of Ca9Al6O18-CaO sorbent, (ii) developing Ca9Al6O18−CaO/xNiO (x = 15, 20, and 25 wt.%) and Ca9Al6O18−CaO/20NiO−yCeO2(y = 5, 10, and 15 wt %) catalyst-sorbent bifunctional materials and studying the influence of CeO2 on the material stability incyclic SESRG/regeneration operation, (iii) proposing a new method for the synthesis of a more readily reducible NiAl2O4 spinel and studying the influence of CeO2 addition on its catalytic performance, and (iv) novel synthesis of two Ni-CaO-based catalyst-sorbent bifunctional materials with highlyuniform distribution of catalytic active sites. (i) CO2 capture performance of Ca9Al6O18-CaO sorbent was investigated in the presence of two concentrations of steam, 2.3 and 9.5 vol. %.The obtained results revealed that the sorbent reactivity was remarkably enhanced for both concentrations of steam injected during carbonation step. In the case of steam addition during calcination, the CO2 capture performance was influenced negatively or positively depending on the concentration of steam. For 2.3 vol.% steam, the sorbent reactivity was worsened, while the presence of 9.5 vol.% steam led to an increase in the CO2capture capacity during 9 initial cycles.(ii) Two series of catalyst-sorbent bifunctional materials were developed for the sustainable production of high-purity hydrogen by SESRG. Using Ca9Al6O18−CaO/xNiO (x = 15,20, and 25 wt.%) materials during five SESRG/regeneration cycles revealed that their reactivity was rapidly deteriorated mainly due to CaO sintering and coke deposition. As a result, the pre-breakthrough time and hydrogen yield decreased notably over five cycles. Interestingly, the addition of CeO2 to the most efficient catalyst (Ca9Al6O18−CaO/20NiO) led to a significant enhancement in material stability during cyclic operation. The bifunctional material promoted with 10 wt.% of CeO2 demonstrated the best performance, with a stable H2purity of ∼98% and H2yield of ∼91% over 20SESRG/regeneration cycles. (iii) A novel method, involving one-or two-step calcination of Ni-Al mixed-metal alkoxide((Ni-Al)-Glycerate), was developed for the synthesis of NiAl2O4 spinel. For comparison purposes, the NiAl2O4 spinel was also synthesized throughthe conventional co-precipitation method followed by two-step calcination technique. The characterization results revealed that the synthesis of NiAl2O4 spinel through two-step calcination of (Ni-Al)-Glycerateresulted in the formation of a more easily reducible catalyst and a more developed porous structure. This sample showed the highest H2yield (76.38 %) and glycerol conversion into gaseous products (95.42 %) when compared to other two samples. In order to avoid or reduce coke formation, 10 wt.% of CeO2 was incorporated into the sample prepared by two-step calcination of (Ni-Al)-Glycerate. The thermogravimetric analysis of the CeO2-promoted catalyst after SRG reaction revealed that the coke formation was almost completely suppressed. The method developed for the synthesis of NiAl2O4 spinel in the previous work was combined with the ethanol/water treatment of CaO-based sorbents to synthesistwo new NiCaO-based catalyst-sorbent bifunctional materials for hydrogen production via SESRG. Cyclic SESRG/regeneration experiments showed that the Ca3Al2O6-CaO/NiO-CeO2 bifunctional material possessed higher activity and stability when compared to NiAl2O4-CaO/NiAl2O4-CeO2. The former one exhibited a high constant H2 purity of around 96% over 10 cycles, while the latter showed a H2 purity of approximately 90% over the first 6 cycles, followed by the further decrease to 86 % over the last 4 cycles. In conclusion, the results presented in this thesis show that SESRG can be a very promising approach for high-purity hydrogen production in a single step, providing that the employed catalyst-sorbent bifunctional materials possess uniform distribution of catalytic and sorption active sites on nanoscale and high resistance against CaO sintering and coke formation. To prepare catalyst-sorbent bifunctional materials with these characteristics, two main approaches were employed in this work: (i) developing new synthesis methods that provide a homogeneous distribution of targeted elements (Ca, Ni, Al, and Ce in this study) and (ii) using CeO2 as a promising promoter to reduce or suppress coke formation and enhance the cyclic stability of CaO particles.

Book excerpt: This work presents the H2 production by glycerol steam reforming (GSR) using as catalysts mixed fluorite-type oxides of Ce-Zr-(Ru/Rh) and Ce-Zr-Co-(Ru/Rh). The effect of the active phase (Ru, Rh, Co-Ru, Co-Rh), the amount of the noble metal (0.5% wt, 1.2 % wt), and the mass CeO2/ZrO2 ratio (0.65/0.35, 0.8/0.2, 0.2/0.8) were studied. The characterisation of the catalysts before test showed that the introduction noble metals favoured the redox properties of the mixed oxides by lowering the temperature of reduction. However only with the presence of Co and the noble metal the reducibility capacity of the mixed oxides increased (% Ce reduced). The redox properties were also enhanced by the higher amount of Ce in the mixed oxide. The presence of the noble metals (Ru/Rh) increases the catalytic activity and stability respect to Ce-Zr and Ce-Zr-Co catalysts. The increase in the amount of noble metal did not present a significant change but the increase in the Ce amount enhanced the stability and selectivity towards H2. The comparison between equivalent series of Ru and Rh catalysts shows that the Rh oxides exhibit a better catalytic behaviour. The catalyst with the best performance towards the production of H2 was the Ce-Zr-Co-Rh mixed oxide rich in cerium. Additional tests were performed using this catalyst and it was found that improvements of the process of GSR can be achieved by modification of the catalytic bed configuration (favour the steam reforming of glycerol decomposition by-products) and by the addition of low quantities of O2 to the reactant flow (improve carbon gasification and catalyst stability).

Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Available in PDF, EPUB and Kindle. Book excerpt: The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.

Book excerpt: Energy recovery from waste resources holds a significant role in the sustainable waste management hierarchy to support the concept of circular economies and to mitigate the challenges of waste originated problems of sanitation, environment, and public health. Today, waste disposal to landfills is the most widely used methodology, particularly in developing countries, because of limited budgets and lack of efficient infrastructure and facilities to maintain efficient and practical global standards. As a consequence, the dump-sites or non-sanitary landfills have become the significant sources of greenhouse gases emissions, soil and water contamination, unpleasant odors, leachate, and disease spreading vectors, flies, and rodents. However, waste can be utilized to produce a range of potential products such as energy, fuels and value-added products under waste biorefineries. A holistic and quantitative view, such as waste biorefinery, on waste management must be linked to the actual country, taking into account its socio-economic situation, local waste sources, and composition, as well as the available markets for the recovered energy and products. Therefore, it is critical to understand that solutions cannot be just copied from one region to the others. In fact, all waste handling, transportation, and treatment can represent a burden to the cities’ environment and macro and micro economics, except for the benefits obtained from recovered materials and energy. Equally significant is a clear and quantitative understanding of the industrial, and public potential of utilizing recovered materials and energy in the markets as these can be reached without exacerbating the environmental issues using excessive transport. The book explores new advancements and discoveries on the development of emerging waste-to-energy technologies, practical implementation, and lessons learned from sustainable wastemanagement practices under waste biorefinery concept, which will accelerate the growth of circular economies in the world. The articles presented in this book have been written by expert researchers and academics working in institutions at different countries across the world including Germany, Greece, Japan, South Korea, China, Saudi Arabia, Pakistan, Indonesia, Malaysia, Iran, and India. The research articles have been arranged into three main subject categories; 1) Resource recovery from waste, 2) Waste to energy technologies and 3) Waste biorefineries. This book will serve as an important resource for research students, academics, industry, policy makers, and government agencies working in the field of integrated waste management, energy and resource recovery, waste to energy technologies, waste biorefineries etc. The editorial team of this book is very grateful to all the authors for their excellent contributions and making the book successful.
