Abstract
The transformation of hydrolytic lignin in 1,4-dioxane at a temperature of 250°C and a pressure of 13.0 MPa and the subsequent hydrogenation of thermal pyrolysis products on a Ru/C catalyst at a temperature of 250°C and a pressure of 10.0 MPa in an autoclave were studied. It has been established that the interaction of hydrolytic lignin with 1,4-dioxane and its catalytic hуdrogenation leads to the splitting of C−O and C−C bonds with the formation of a mixture of products: soluble phenol-derivative oligomers and monomers, products of their hydrogenolysis and hydrogenation, as well as a mixture of C1−C5 gas hydrocarbons and C2−C5 alcohols, ethers − formed mainly under reaction conditions during the destruction of the solvent − 1,4-dioxane.
