Аннотация:The study presents the results of cellulose hydrolytic hydrogenation process in subcritical water in the presence of Ni, Fe, Pt, Pd, Au and Ru-containing catalysts based on hypercrosslinked polystyrene (HPS) MN-270 and its functionalized analogues: NH2-HPS (MN-100) and SO3H-HPS (MN-500). Nonfunctionalized HPS was shown to be the optimal carrier for these catalysts, and Ru-containing catalysts are the most active in the process of cellulose conversion into polyols. In this case the total yield of sorbitol and mannitol was 50% on the average at 85% cellulose conversion. On the basis of the experimental and computed data the pathway of hydrolytic hydrogenation of cellulose was suggested.
