This book is part of a two-volume work that offers a unique blend of information on realistic evaluations of catalyst-based synthesis processes using green chemistry principles and the environmental sustainability applications of such processes for biomass conversion, refining, and petrochemical production. The volumes provide a comprehensive resource of state-of-the-art technologies and green chemistry methodologies from researchers, academics, and chemical and manufacturing industrial scientists. The work will be of interest to professors, researchers, and practitioners in clean energy catalysis, green chemistry, chemical engineering and manufacturing, and environmental sustainability. This volume focuses on catalyst synthesis and green chemistry applications for petrochemical and refining processes. While most books on the subject focus on catalyst use for conventional crude, fuel-oriented refineries, this book emphasizes recent transitions to petrochemical refineries with the goal of evaluating how green chemistry applications can produce clean energy through petrochemical industrial means. The majority of the chapters are contributed by industrial researchers and technicians and address various petrochemical processes, including hydrotreating, hydrocracking, flue gas treatment and isomerization catalysts.

Prof. Kamal Kishore Pant is a Petrotech Chair Professor and Head of the Department of Chemical Engineering at IIT Delhi, and also Joint faculty CRDT, IIT Delhi, Adjunct Faculty at the University of Saskatchewan as well as Honorary Faculty at the University of Queensland, Australia. Prof. Pant's research contribution involves a wide range of innovative studies covering both theoretical and experimental aspects of heterogeneous catalysis for hydrocarbon conversion, CO2 capture and conversion, coal to chemical, bioenergy, waste to wealth, and value-added chemicals. Prof. Pant has 30 years of research and teaching experience during which he published 160+ Journal articles, book chapters, and patents, having more than 8000 citations and is granted several national and international patents. Most of Prof. Pant's research work is aligned with the internationally-focused research areas that include the development of coal to methanol process, CO2 capture, and conversion, disposal of e-waste and precious metals recovery, waste plastic to liquid fuel technology, as well as biofuels production from residual agro biomass to thwart stubble burning. Prof. Pant is amongst the leading researchers in India working on solving the problems of accumulating electronic waste. Besides, Prof. Pant has extensively worked to develop novel catalysts for the direct conversion of Natural gas to pure hydrogen and Carbon nanotubes. Prof. Pant has also significantly contributed to developing novel catalysts for the dry reforming of methane and steam/oxidative steam reforming of Bioethanol and Bio-oil compounds, converting plastic waste and biomass to value-added chemicals which are highly appreciable in utilizing renewable sources in the country.
