Abstract

This paper presents the latest significant advances in the Ru-containing catalysts application in the reductive processing of lignin and lignocellulosic biomass. The features of the catalytic action of Ru-catalysts in aqueous and water-alcohol media are also considered in comparison with other platinum group metals. The performance of various Ru-based catalytic systems in the processes of lignin depolymerization and processing of lignocellulosic biomass is compared. By modifying and designing supports to provide them acidic properties, a mesoporous structure promoting good reagents transport, and improved distribution of Ru nanoparticles, the efficiency of ruthenium catalysts can be significantly improved. Ru-based catalysts are the most efficient in the processes of reductive processing of lignocellulosic biomass and lignin in aqueous media compared to other platinum group metals
