Advanced Biomass Gasification: New Concepts for Efficiency Increase and Product Flexibility provides a thorough overview on new concepts in biomass gasification and consolidated information on advances for process integration and combination, which could otherwise only be gained by reading a high number of journal publications. Heidenreich, Müller and Foscolo, highly respected experts in this field, start their exploration with the compact UNIQUE reactor, gasification and pyrolysis, gasification and combustion, and catalysts and membranes. The authors then examine biomass pre-treatment processes, taking into account the energy balance of the overall conversion process, and look into oxygen-steam gasification and solutions for air separation, including new options for integration of O2-membranes into the gasifier. Several polygeneration strategies are covered, including combined heat and power (CHP) production with synthetic natural gas (SNG), biofuels and hydrogen, and new cutting-edge concepts, such as plasma gasification, supercritical water gasification, and catalytic gasification, which allows for insights on the future technological outlook of the area. This book is then a valuable resource for industry and academia-based researchers, as well as graduate students in the energy and chemical sectors with interest in biomass gasification, especially in areas of power engineering, bioenergy, chemical engineering, and catalysis. Explores state-of-the-art technologies that allow for greater efficiency and flexibility in gasification, including process integration, combination, and polygeneration strategies Consolidates information that was, up until now, scattered among several sources, including journal articles Provides a valuable resource for industry and academia-based researchers, as well as graduate students in the energy and chemical sectors with interest in biomass gasification, especially in areas of power engineering, bioenergy, chemical engineering, and catalysis

Skyrocketing energy costs have spurred renewed interest in coal gasification. Currently available information on this subject needs to be updated, however, and focused on specific coals and end products. For example, carbon capture and sequestration, previously given little attention, now has a prominent role in coal conversion processes. This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes. The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes. The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are covered. Emphasis is given to the selection of gasification technology based on the type of coal fed to the gasifier and desired end product: E.g., lower temperature gasifiers produce substantial quantities of methane, which is undesirable in an ammonia synthesis feed. This book also reviews gasification kinetics which is informed by recent papers and process design studies by the US Department of Energy and other groups, and also largely ignored by other gasification books. • Approaches coal gasification and related technologies from a process engineering point of view, providing a perspective for engineers and scientists who analyze and improve components of coal conversion processes • Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes • Emphasizes the importance of the coal types fed to the gasifier and desired end products • Covers gasification kinetics, which was largely ignored by other gasification books Provides a perspective for engineers and scientists who analyze and improve components of the coal conversion processes Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes Covers gasification kinetics, which was largely ignored by other gasification books

Gasification of Waste Materials: Technologies for Generating Energy, Gas and Chemicals from MSW, Biomass, Non-recycled Plastics, Sludges and Wet Solid Wastes explores the most recent gasification technologies developing worldwide to convert waste solids to energy and synthesis gas and chemical products. The authors examine the thermodynamic aspects, accepted reaction mechanisms and kinetic constraints of using municipal solid waste (MSW), biomass, non-recycled plastics (NRP), sludges and wet solid wastes as feedstock. They identify the distinctions between pyrolysis, gasification, plasma, hydrothermal gasification, and supercritical systems. A comprehensive summary of laboratory and demonstration activities is presented, as well as field scale systems that have been in operation using solid waste streams as input, highlighting their areas of disconnect and alignment. The book also provides a summary of information on emissions from the stack, comparing them with other thermal conversion systems using similar feedstock. It then goes on to assess the areas that must be improved to ensure gasification systems become as successful as combustion systems operating on waste streams, ranging from feedstock processing to gasifier output gas clean-up, downstream system requirements and corrosion. The economics and future projections for waste gasification systems are also discussed. For its consolidation of the current technical knowledge, this text is recommended for engineering researchers, graduate students, industry professionals, municipal engineers and decision makers when planning, designing and deploying waste to energy projects, especially those using MSW as feedstock. Provides field demonstrations of large scale systems, their results and the challenges that need to be overcome when developing commercial applications and possible solutions Presents the most recent technologies in lab and demonstration scale Examines the critical development needs and real life challenges for the deployment of waste to energy technologies Provides information on the economics and sustainability of these technologies, as well as their future perspectives

Most coveted energy forms nowadays are gas in nature and electricity due to their environmental cleanness and convenience. Recently, gasification market trend is starting to switch to low-grade feedstock such as biomass, wastes, and low-rank coal that are still not properly utilized. In this sense, the most promising area of development in gasification field lies in low-grade feedstock that should be converted to more user-friendly gas or electricity form in utilization. This book tried to shed light on the works on gasification from many parts of the world and thus can feel the technology status and the areas of interest regarding gasification for low-grade feedstock.

Abstract: Pongamia residue (shells) is the byproduct from the biodiesel processing industry, which is a lignocellulosic biomass material. It is not suitable as feedstock in downdraft wood gasifier due to low bulk density (146kg/m 3 ) of shells as compared to wood (more than 350kg/m 3 ). Pelletization and gasification of pelletized shells was carried out in the present work. The heat transfer analysis in pellets of 17mm and 11.5mm was also carried out to evaluate thermal properties of this biomass. Shell pellets of 17mm and 11.5mm diameter and length in the range of 10–60mm were gasified in a 20kWe downdraft wood gasifier. The complete gasification of pellets with 17mm diameter could not be achieved because of less porosity and presence of larger thermal gradient within the pellets. The gasification efficiency was 73% for 17mm diameter pellets which is lower than that of 11.5mm diameter pellets which was 95%. The calorific value of producer gas generated from smaller diameter pellets was higher (4.66MJ/Nm 3 ) as compared to larger diameter pellets (3.98MJ/Nm 3 ). Tar formation during gasification of smaller diameter pellets was low as compared to larger diameter pellets. Highlights: The gasification efficiency for 17 mm and 11.5 mm diameter pellets were 73 and 95% respectively. The complete gasification of pellets with 17 mm diameter could not be achieved. The quality of producer gas was high for smaller diameter pellets. Tar formation during gasification of smaller diameter pellets was low as compared to larger diameter pellets.
