Cellulose hydrogenolysis with the use of the catalysts supported on hypercrosslinked polystyrene

Abstract

Abstract. The study presents the results of cellulose hydrolytic hydrogenation process in subcritical water in the presence of Ru-containing catalysts based on hypercrosslinked polystyrene (HPS) MN-270 and its functionalized analogues: NH2-HPS (MN-100) and SO3H-HPS (MN-500). It was shown that the replacement of the traditional support (carbon) by HPS increases the yield of the main cellulose conversion products -polyols -important intermediates for the chemical industry. The catalysts were characterized using transmission electron microscopy (TEM), high resolution TEM, and porosity measurements. Catalytic studies demonstrated that the catalyst containing 1.0% Ru and based on MN-270 is the most active. The total yield of sorbitol and mannitol was 50% on the average at 85% cellulose conversion.

Microporous Hyper-Crosslinked Polystyrenes and Nanocomposites with High Adsorption Properties: A Review

“…Moreover, with an interesting strategy, Ru-containing catalysts were also realized on HCL polystyrene resins, either unfunctionalized, or functionalized with amino and sulphate groups. The catalyst based on unfunctionalized resin and containing 1.0 wt % Ru was found the most active for cellulose hydrogenolysis to sorbitol and mannitol [ 98 ].…”
