Available in PDF, EPUB and Kindle. Book excerpt: Supercritical water gasification (SCWG) is an innovative, modern, and effective destruction process for the treatment of organic compounds. Hydrogen production using SCWG of biomass or waste feedstocks is a promising approach towards cleaner fuel production while simultaneously providing novel solution for hard-to-treat organic wastes. The main premise of this work was to experimentally examine real waste biomass sources i.e. hog manure and waste biomass model compounds using gasification in SCW while examining various commercial catalysts. The improvement of the SCWG process requires a understanding of the waste/biomass reaction chemistry, and thus a knowledge of the reaction mechanisms is critically important for proper catalyst selection and design. The main possible reactions that occurred through the formation and disappearance of intermediate compounds as well as the final gaseous and liquid final products are reported. In this work, gasification and partial oxidation of glucose 0.25 Molari ty (M) was conducted using different metallic Ni loadings (7.5, 11, and 18 wt %) on different cata lyst supports (? -Al 2 O 3 and? -Al 2 O 3) in supercritical water at 400-500°C, and compared with a commercial catalyst (65 wt % Ni on Silica-Alumina). Results showed that the presence of metallic Nickel increases the yield of gases and the total g as yield increased with increasing nickel in the 7.5-18 wt % Ni/Al 2 O 3 catalyst. This study showed that the same hydrogen yield can be obtained from the synthesized low nickel alumina loading (18 wt %) catalyst as the high (65 wt %) nickel on silica-alumina commerci al catalyst. In this work, oleic acid was examined as a model compound for lipids. Results showed that an increase of temperature coupled with the use of cata lyst enhanced the gas yield dramatically. The H 2 yield was 15 mol/ mol oleic acid converted using both the pelletilized Ru/Al 2 O 3 and powder Ni/Silica-alumina catalysts which yielded 4 times higher than the calculated equilibrium yield of 3.5 mol/mol oleic ac id fed. The composition of residual liquid products was studied and a generalized rea ction pathway of oleic acid decomposition in SCW reported. Cysteine gasification in supercritical water in the presenc e of Ru/Al 2 O 3, Ru/AC and activated carbon (AC) catalysts was also investigated. The main sulfur-containing compound in the gaseous effluents in all experiments was H 2 S. It was found that the formation of H 2 S was neither dependent on temperature nor on the catalyst. The composition of residual liquid products revealed the presence of residu al organic sulfur components that include diethyl sulfide, diethyl tri sulfide, and ethanone. A generalized reaction pathway for organo-sulfur compounds was reported. The catalytic co-gasification of starch and catechol as model s of carbohydrates and phenol compounds was investigated. Employing TiO 2 as a catalyst alone had no significant effect on the H 2 yield but when combined with CaO increased the hydrogen yield by 35%, while promoting higher total carbon (TOC) reduction efficiencies. The process liquid effluent characterization showed that the major non-pol ar components were phenol, substituted phenols, and cresols. An overall reaction scheme was provided. Catalytic hydrogen production with various catalysts from hog ma nure using supercritical water partial oxidation was investigated. The orde r of H 2 production was the following: Pd/AC> Ru/Al 2 O 3> Ru/AC> AC> NaOH. A 35% reduction in the H 2 and CH 4 yields was observed in the sequential gasification partial oxidati on (oxidant at an 80% of theoretical requirement) experiments compared to the gasif ication experiments (catalyst only). Moreover, this reduction in gas yields coincided wit h a 45% reduction in the liquid effluent chemical oxygen demand (COD), 60% reduction of the a mmonia concentration in the liquid effluent, and 20% reduction in the H 2 S concentration in the effluent gas. The scientific contribution of this study culminated in the development of a qualitative mechanistic understanding of the reaction chemistry of organic matters presented in waste streams such as waste biomass, sewage sludge, and hog manure. This understanding of the SCW reaction chemistry is required for the pote ntial applications of SCW for energy recovery from waste streams through hydrogen production.

Available in PDF, EPUB and Kindle. Book excerpt: Supercritical water is a unique reaction medium with emerging applications in waste destruction, fuel generation, and material synthesis. The high temperatures and pressures necessary to bring water to the supercritical state create a kinetically and thermodynamically advantageous environment for redox reactions to occur, with minimized mass transfer limitations. Supercritical water acts both as reactant and reaction medium, facilitating the rapid decomposition of many organic molecules into hydrogen-rich gas. As a waste-to-energy technology, supercritical water gasification shows promise for converting organic waste, especially wet waste, into green hydrogen. Despite decades of interest in supercritical water gasification and oxidation, fundamental knowledge of reaction chemistry in supercritical water remains limited. It is relevant to study the chemistry of simple model compounds in supercritical water as a means of elucidating reaction phenomena occurring with common compound classes or functional groups. A continuous, tubular supercritical water reactor facilitates novel studies of reaction kinetics in supercritical water. In situ Raman spectroscopy allows for real-time monitoring of reaction products, short experimentation times, and rapid identification and quantification of reaction products. Through multiple studies investigating reaction kinetics of model compounds in the gasification environment, chemical reaction routes and mechanisms of several model compounds are determined under varied conditions. As a proof-of-concept study to demonstrate the validity of using Raman spectroscopy for determining product yields, the reaction kinetics of formic acid (HCOOH) in 25 MPa water are quantified for subcritical and supercritical temperatures between 300 and 430 °C. In situ Raman spectroscopy facilitates precise, time-resolved data collection. First-order reaction behavior is not observed during gasification of methanol, ethanol, or isopropyl alcohol in supercritical water between 500 and 560 °C. Chain-branching free radical reaction mechanisms are inferred to drive the decomposition of alcohols in supercritical water, and the heterogeneous catalyst of the reactor wall surface is significant for initiating radical reactions. Global reaction pathways are proposed, and mechanisms for free radical initiation, propagation, and termination are discussed. Ethanol is also studied under partially oxidative conditions at 500 to 530 °C, where intermediate reaction products counterintuitively polymerize to form char. A deeper understanding of reaction mechanisms in supercritical water is gained, lending insight towards the conditions necessary to maximize gaseous yields and minimize char buildup.

This book was released on 2013 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study targets to convert aqueous fraction of fast pyrolysis oil into methane and hydrogen gases via supercritical water gasification (SCWG). Water above its critical point is referred to as supercritical water, which has unique properties such as a loss of hydrogen bonding, becoming an excellent solvent for organic compounds. In this thesis, SCWG was used to gasify slurry materials into high calorific gases including CH4 and H2. Production selectivity towards more methane or hydrogen was affectively controlled by operational conditions. However, in the absence of catalyst (bank test), gas formation was very minimal. SCWG of glucose as an organic model compound was studied to screen the best catalyst for methane production. Ni20%Ru2%/-Al2O3 catalyst was able to convert all carbon in glucose to gases at a temperature of as low as 500 °C and weight-hourly space velocity (WHSV) of 3 h-1. This catalyst significantly promoted methane production and produced 0.5 mol methane per mole of carbon in the glucose feedstock. High stability and activity of this catalyst were observed during 20 hours on stream. It was also found out from this study that nickel loading, temperature, substrate concentration and feeding rate or WHSV greatly affected carbon conversion and yields of CH4 and H2 in SCWG. For instance, higher temperatures favor hydrogen formation while lower temperatures promote methane yield. Moreover, the Ni20%Ru2%/-Al2O3 catalyst demonstrated to be active for gasifying the aqueous fraction of fast pyrolysis oil via SCWG. Besides, the aqueous fraction of pyrolysis oil was gasified to a high extent in the presence of this catalyst, and 0.9 mol/mol of carbon in feedstock (2.98 wt.% C) was converted into CH4 and CO2 at 700 °C.

This book was released on 2011 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microreactors offer high rates of heat transfer able to intensify highly endothermic biomass reforming reactions in supercritical water. In this study, two continuous flow microreactor configurations were used to gasify biomass constituents in supercritical water. The first reactor configuration was a micro diameter stainless steel or Hastelloy tube (508 um - 762 um) imbedded into a reactor block. The reactor provided high rates of heat transfer to the reacting fluid to sustain an isothermal reaction temperature and was used to elucidate interactions between phenol, a lignin model compound, and xylose, a hemicellulose model compound, during co-gasification. In addition, a reaction mechanism and kinetics for phenol and xylose gasification by supercritical were estimated. The second microreactor configuration studied was a parallel channel Hastelloy microreactor. The reactor consisted of 14 parallel rectangular microchannels (1000 um by 127 um) integrated into a single contiguous reactor block by diffusion bonding a series of shims between two header plates. Fabrication of the reactor from Hastelloy C-276, a high nickel content alloy, substantially intensified biomass gasification reactions and promoted the water gas shift and methanation reactions due to its high catalytic activity and the large surface area to volume ratio in the microchannel. The dispersion and channel flow distribution in the microchannel reactor was characterized experimentally and modeled using computational fluid dynamics by a tracer pulse study. Furthermore, computational fluid dynamics were used to investigate the effect of endothermic biomass reforming reactions and the average fluid Reynolds number on the reaction temperature. Lastly, xylose was completely gasified to hydrogen and carbon dioxide in the parallel channel microreactor at 650°C and 250 bar within a 1.4 second residence time.

Book excerpt: This book systematically presents the technical aspects of supercritical water oxidation and supercritical water gasification for energy and environmental applications, which include reactor design, construction materials, corrosion, salt precipitation, etc. The book provides a comprehensive introduction to the properties of supercritical water, and the industrial applications, reaction mechanisms and reaction kinetics of supercritical water oxidation (SCWO) and supercritical water gasification (SCWG). The reactions occurring in supercritical water are complex, and studying their reaction mechanisms is of great importance for the development of supercritical water processing technologies. Accordingly, the book explains the oxidative mechanisms and kinetics of organic matter in supercritical water in detail. However, the harsh reaction conditions in supercritical water can easily create severe reactor corrosion and salt deposition problems. Therefore, the book also comprehensively reports on the mechanism analysis, state of research, and development trends regarding these two problems. Lastly, the book summarizes the development of supercritical water processing technologies, including studies on SCWO and SCWG, as well as near-zero-emission systems of pollutants based on SCWO technology. In short, the book provides a wealth of valuable information for all readers who are interested in using SCWO for organic waste treatment, and in using SCWG for hydrogen production with wet biomass.

Available in PDF, EPUB and Kindle. Book excerpt: Supercritical water gasification (SCWG) is an emerging technology with synergistic applications in renewable energy and waste processing. Supercritical water (SCW) functions as a green reaction medium during the gasification process, serving to dissolve and decompose complex organic molecules via ionic, radical, hydrolysis, and pyrolysis reaction mechanisms. Researchers investigate the decomposition of model compounds in order to predict product yields and conversion efficiencies during the gasification of heterogeneous biomass waste, food waste, sewage sludge, and other available feedstocks. Continuous, laboratory-scale reactors are often employed to study reaction kinetics, pathways, and mechanisms. This chapter synthesizes previous work investigating model compound gasification in continuous supercritical water reactors (SCWRs). A summary of continuous reactor design strategies is presented for practical benefit, followed by a discussion on reaction chemistry in the supercritical water environment. Reaction pathways and mechanisms have been investigated for several model compounds, lending insight toward the conditions needed for the complete conversion of real-world feedstocks. Several studies assume first-order reaction kinetics and propose Arrhenius parameters for the decomposition reaction. The first-order rate assumption must be carefully evaluated, and the applicable temperature range must be specified. Opportunities for further research are discussed.
