Biomass conversion into drop-in chemicals using novel heterogeneous bulk- and nano-scale catalysts is currently a hot research topic with the aim of replacing petrochemicals in the chemical industry. Considering the importance of this subject to the scientific community, Advanced Catalysis for Drop-in Chemicals provides the latest developments in the catalytic synthesis of drop-in chemicals mainly from lignocellulose, carbohydrates (cellulose, hemicellulose, C6 and C5 sugars, and their derivatives), lignin, and glycerol. The role of both heterogeneous bulk solid and nanostructured catalysts, along with their advantages and disadvantages for drop-in chemicals synthesis are critically summarized. Addressing the frontiers and prospects for using drop-in chemicals in place of petrochemicals in the chemical industry is also a key topic of this book. © 2022 Elsevier Inc. All rights reserved.
