Аннотация: <jats:p>The study is devoted to the influence of the composition of the water-ethanol solvent on the process of thermocatalytic conversion of spruce wood using the bifunctional catalyst Ru/C. The experiments were carried out at different ratios of ethanol and water (95/5, 80/20, 50/50%) in an argon environment at a temperature of 2Показать полностью25 °C and a pressure of 3.4–4.5 MPa. It was found that an increase in the proportion of water in the solvent to 50% leads to an increase in wood conversion from 49.5% to 67.4% in the presence of the Ru/C catalyst, and also contributes to obtaining a cellulose product with a minimum content of lignin (3.0%) and hemicelluloses (1.3%). The analysis of liquid products revealed an increase in the proportion of water-soluble oligosaccharides and a decrease in the yield of phenolic monomers when diluting ethanol with water. The results demonstrate the potential of using water-alcohol mixtures to optimize the processes of reductive catalytic fractionation of lignocellulosic biomass.</jats:p>
