This book was released on 2020 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pyrolyzation of waste plastic and lignocellulosic material feedstocks increases the hydrogen/carbon ratio of the plastic-biomass mixture for feedstock pyrolysis and may be advantageous for the refinement of the properties of the pyrolyzed oil, which can be directly used as fuel without any upgrade requirements by catalytic hydrodeoxygenation reactions. In this paper, high-density polyethylene (HDPE) and brown salwood were tested in a custom-built laboratory-scale fixed-bed reactor to investigate the co-pyrolysis reaction at a temperature ranging from 500 to 650 °C, nitrogen sweeping flow rate ranging from 40 to 160 mL min -1 , and HDPE to biomass ratio ranging from 0.1 to 0.9. The results reveal that the temperature mostly influences the pyrolysis products, whereas increasing the temperature to 600 °C encourages pyrolysis oil production, and its yield reaches 48.13 wt.%, which decreases to 27.92 wt.% as the reaction temperature increases to 650 °C due to secondary cracking reactions producing noncondensable gas rich in hydrocarbons. Physicochemical analysis of the pyrolyzed organic phase revealed a gross calorific heating value up to approximately 38.19 MJ kg -1 . Additionally, co-pyrolysis with HDPE improved the production of furans, and acid derivatives were obtained in the aqueous fraction via the thermal conversion of hemicellulose and lignin, whereas the obtained char exhibited a notably low surface area and few superficial micropores.

Book excerpt: Biomass pyrolysis has been practised for centuries in the manufacture of charcoal for industry and leisure. Only in the last two decades, however, has attention focussed on a better understanding of the science and technology, with the resultant benefits of better designed and controlled processes that give high yields of liquid products. These liquids, or 'bio-oil' as it is referred to, can be used in a variety of ways: -combustion to replace conventional fuel oil in boilers, process equipment such as kilns and in gas turbines for power generation; -upgrading by hydrotreating or with zeolites to gasoline, diesel and other hydrocarbon fuels, of chemicals; --extraction and upgrading to fuel additives and chemical specialities. Any charcoal produced can also be utilised to form char- water slurries, analogous to coal-water slurries, or bioi-oil slurries which may be used as liquid fuels in many combustion applications. A group of experts was set up in the EC Energy from Biomass programme to evaluate the status and opportunities for deriving useful liquid products from biomass pyrolysis. This book is a report of their findings and conclusions. It forms an authoritative guide to the wide range of technologies employed in biomass pyrolysis, and product upgrading, utilisation and characterisation. Recommendations and conclusions are included to identify promising areas of research and development that will be of value to researchers, planners and companies throughout the world.

Available in PDF, EPUB and Kindle. Book excerpt: Bio-oil is a liquid fuel that can be produced from various lignocellulosic feedstocks via fast pyrolysis. It is a complex mixture comprised of hundreds of highly oxygenated organic compounds originating from lignin and carbohydrates and is recognized as a clean renewable bio-fuel, an attractive alternative to fossil fuels. It can be easily transported and used directly in boilers and modified turbines or upgraded/fractionated for drop in fuels or chemical production. Proper bio-oil characterization is important in optimizing the pyrolysis process, bio-oil upgrading and utilization, and its stabilization for long-term storage. With this in mind, research has been undertaken to develop better techniques to rapidly profile the composition of whole bio-oil samples, and an accelerated aging study performed to determine why bio-oil is unstable upon storage. Pyrolysis-GC/MS and TLC-FID were used as tools to differentiate bio-oils of different lignocellulosic biomasses, and among thermal-cracking (upgrading) fractions. Results showed that birch bio-oil had high syringol derivatives compared to pine and barley straw bio-oils which had higher guaiacol and non-methoxy-phenolic compounds, respectively, compared with birch bio-oil. TLC-FID was successful in bio-oil differentiation, showing diagnostic chromatographic profile differences. Direct infusion-ESI-ion trap MS and ESI-ion trap MS2 were successfully used in the analysis of forest-residue bio-oil and reference bio-oils from cellulose and hardwood lignin dissolved in methanol:water. NH4Cl can be used as a dopant to distinguish carbohydrate-derived products from other bio-oil components. NaOH and NaCl dopants resulted in the highest intensity peaks in negative ion mode and positive mode, respectively. Tandem MS, that is, ESI-Ion Trap MS2 was a successful tool for the confirmation of individual target ions such as levoglucosan and cellobiosan and for structural insight into lignin products. In accelerated aging (at 80 °C for 1, 3 and 7 days) studies, the physical and chemical properties of bio-oil from ash wood (produced from a pilot-scale auger pyrolyzer) and birch wood (lab-scale pyrolyzer) were monitored in order to identify the factors responsible for bio-oil instability. Water content, viscosity, and decomposition temperature (by TGA) increased for both bio-oil samples with aging. Chemical analysis showed reduction in amount of most of the bio-oil components as aging progressed, typically for are olefins and aldehydes. The oils remained a single phase throughout until the 7th day.

Book excerpt: Biomass is widely considered as a potential alternative to dwindling fossil fuel reserves. There is a large variety of biomass sources (oleaginous, lignocellulosic, algae, etc.), with many possible conversion routes and products. Currently, biomass is not just viewed as a source of biofuels, but also as an interesting feedstock for the production of bio-based chemicals that could largely replace petrochemicals. In this context, the search for new sustainable and efficient alternatives to fossil sources is gaining increasing relevance within the chemical industry. There, the role of catalysis is often critical for the development of clean and sustainable processes, aiming to produce commodity chemicals or liquid fuels with a high efficiency and atom economy. This book gathers works at the cutting edge of investigation in the application of catalysis, for the sustainable conversion of biomass into biofuels and bio-based chemicals.

Available in PDF, EPUB and Kindle. Book excerpt: Fast pyrolysis of biomass is a next-generation biofuels production process that is capable of converting solid lignocellulosic materials (in their raw form) to a transportable liquid (bio-oil) which can be catalytically hydrogenated to fuels and chemicals. Pyrolysis reactors depolymerize solid biomass by heating the feedstock (in the absence of oxygen) up to high temperatures (400 - 600 °C) to produce a short-lived intermediate liquid phase (only a few seconds), which ultimately breaks down to form small (1-6 carbon) oxygenates. These vapor-products can then be condensed at room temperature to produce liquid bio-oil. While biomass fast pyrolysis has enormous potential to produce renewable fuels, an understanding of the fundamental chemistry and transport processes of biomass pyrolysis to produce bio-oil is not available in the literature. This work utilizes co-pyrolysis and isotopic labeling to study the liquid-phase secondary reactions of levoglucosan to form anhydrosugars, pyrans, and light oxygenates. Isotopic labeling studies also reveal that hydrogen exchange is a critical component of levoglucosan deoxygenation. Next, the effects of pyrolysis reaction temperature and sample length scale are discussed. These studies revealed that the yield of total furan rings (i.e., all products containing a five-membered furan ring) does not change significantly with increased reaction temperature compared to other pyrolysis products, such as light oxygenates and anhydrosugars. However, the functional groups bound to the furan ring (e.g., alcohols and aldehydes) are easily cleaved to produce smaller furans. This chemistry was targeted by impregnating cellulose with palladium on carbon to selectively decarbonylate oxygenated furans within liquid intermediate cellulose to form deoxygenated furans resulting in a more stable bio-oil. The last part of this thesis, a new experimental technique, Spatiotemporally-Resolved Diffuse Reflectance in situ Spectroscopy of Particles (STR-DRiSP), which is capable of measuring biomass composition during fast pyrolysis with high spatial (ten micron) and temporal (one millisecond) resolution is developed. Compositional data were compared with a comprehensive two-dimensional single particle model. The STR-DRiSP technique can be used to determine the transport-limited kinetic parameters of biomass decomposition for a wide variety of biomass feedstocks.
