Due to environmental concerns and the depletion of fossil resources, the
sustainable utilization of biomass for producing valuable chemicals and fuels has
gained substantial attention in recent years. Advanced solid base catalysts have
emerged as essential tools in this attempt, with high catalytic efficiency, improved
selectivity, and low environmental impact. The present chapter provides an in-depth
exploration of various advanced solid base catalysts like metal oxides, alkali metalsupported metal oxides, alkaline earth metal oxides, waste solid base catalysts, clay
materials, and mesoporous solid base catalysts, etc., for transforming biomass and its
derivatives into value-added products. Specific processes covered include
transesterification of oils, aldol condensation of biomass-derived compounds,
depolymerization of lignin, glycerol transesterification for carbonate production, and so
on.
Keywords: Aldol condensation, Glycerol carbonate, Glycerol, Lignin depolymerization, Oils, Solid base catalysts, Transesterification.
