Effects of zeolite porosity and acidity on catalytic conversion of carbohydrates to bio-based chemicals: a review

Abstract

Optimizing the production process of high value-added chemicals derived from renewable biomass holds immense promise for clean energy utilization and environmental sustainability. The abundant acidic sites and distinctive pore structures of zeolites serve as critical catalysts in improving the effectiveness of carbohydrates conversion and enabling the selective preparation of bio-based chemicals. This approach not only maximizes the utilization of renewable resources but also aligns with the imperative of environmental protection. This review presents an extensive overview of the latest advancements in utilizing zeolites as catalysts for converting carbohydrate biomass into bio-based chemicals. Emphasis is placed on elucidating the acidic properties and pore structures of zeolites and their profound impact on the carbohydrates conversion process. Furthermore, the review evaluates future directions for developing zeolite-catalyzed biomass conversion, aiming to offer insights into achieving sustainable and efficient utilization of biomass resources.
