Cellulose Hydrolytic Hydrogenation in Subcritical Water with the Use of the New Type of the Catalysts
Authors: , , , , , , ,
Abstract: The study presents the results of cellulose hydrolytic hydrogenation process in subcritical water in the presence of Ru-containing catalyst based on hypercrosslinked polystyrene (HPS) and its functionalized analogues. 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.
