Progressive Thermochemical Biorefining Technologies

Considering the deleterious impacts of fossil fuels on the environmental and natural ecosystems, it has become imperative to make a paradigm shift toward renewable fuels, chemicals, and materials. The exhaustive everyday usage of fossil fuels and processed petrochemical products are the leading causes for the increase in greenhouse gas emissions, global warming, climate changes, acid rain, ozone layer depletion, pollution of air, water, and soil as well as for the accumulation of nonbiodegradable materials in the soil and oceans. On the contrary, biofuels, biochemicals, and biomaterials derived from renewable wastes such as nonedible plant biomass (e.g., agricultural and forestry biomass), energy crops, microalgae, municipal solid waste, sewage sludge, and other biogenic residues seem to be carbon neutral. Therefore, the global interest in biorefining technologies, especially thermochemical and biological conversion processes, is gaining momentum in academic and industrial perspectives. Progressive Thermochemical Biorefining Technologies offers all-inclusive coverage of the most crucial topics as follows: State-of-the-art information on the production and utilization of biofuels through thermochemical biorefining technologies Conversion of waste biomass through pyrolysis, liquefaction, torrefaction, carbonization, gasification, reforming, and other clean technologies Waste-to-energy/chemical generation Fuel upgrading technologies Techno-economic analysis and life-cycle assessment of biorefining processes Specifically designed to be instantly applicable, this volume serves as a reference book for undergraduate and graduate students, scientific investigators, and research scholars working in the areas relating to energy and fuels.

Innovations in Thermochemical Technologies for Biofuel Processing broadly covers current technologies in alternate fuels and chemical production, a few of which include biomass-to-liquid, biomass-to-gas and gas-to-liquid biomass conversion technologies. The topics in this book include elaborative discussions on biomass feedstocks, biomass-to-liquid technologies (liquefaction, pyrolysis and transesterification), biomass-to-gas technologies (gasification), gas-to-liquid technologies (syngas fermentation and Fischer-Tropsch synthesis), co-processing technologies, fuel upgrading technologies (hydrotreating and reforming), novel catalyst development for biorefining, biorefining process optimization, unit operations, reaction kinetics, artificial neural network, and much more. The book comprehensively discusses the strengths, weaknesses, opportunities and threats of notable biofuels (e.g., bio-oil, biocrude oil, biodiesel, bioethanol, biobutanol, bio-jet fuels, biohydrogen, biomethane, synthesis gas, hydrocarbon fuels, etc.). Addresses solutions for clean fuel, energy security, waste management, waste valorization, reduced greenhouse gas emissions, carbon capture and sequestration, circular economy and climate change mitigation Includes applications of thermochemical conversion and reforming technologies for waste biomass to biofuels Covers current technologies in alternate fuels and chemicals production, a few of which include conversion technologies (i.e., liquefaction, gasification, pyrolysis, torrefaction, transesterification, organic transformation, carbon-carbon and carbon-heteroatom coupling reactions, oxidation, and reforming processes, etc.), hydrotreating technologies (i.e., hydrogenation, hydrodesulfurization, hydrodenitrogenation, hydrodearomatization and hydrodemetalization) and catalytic processes.

This title includes a number of Open Access chapters. Increasing attention is being paid to the valorization of solid wastes—converting them into energy or other useful products. This book describes recent research into methodologies and technologies for managing various forms of solid waste, while at the same time generating energy and revenue with less impact on the environment. Topics include combustion, gasification, pyrolysis, and hydrothermal carbonization. The transition from a fossil fuel-based economy to a more sustainable economy will require a solid foundation of ongoing scientific research. The editor of this compendium, a well-respected researcher in the field, has selected studies that help to build that foundation.
