| Özet: | Заглавие с экрана The hydrolysis-hydrogenation is one of the most perspective ways of cellulose processing to valuable sorbitol product. It is widely used in the food and pharmaceutical industries as a sweetener and seems to be a perspective platform molecule for the chemical industry. The aim of the present work was the development of solid bifunctional (acid-reductive) catalyst based on Ru-HPA/ZrO2 and Ru-HPA/Nb2O5 for the production of sorbitol from inedible cellulose. Four samples of 3%Ru-HPA/ZrO2 and Ru-HPA/Nb2O5 differed from each other by the support calcination temperature (450 °C and 550 °C) were prepared and characterized by N2 absorption, TEM, IR, AES. High stability of the catalysts under the reaction conditions was demonstrated. The catalysts were tested in the hydrolysis-hydrogenation of microcrystalline cellulose to sorbitol under 180 °C and 50 bar of H2. HPLC analysis demonstrated for sorbitol to be the main reaction product. Mannitol and negligible amount of glucose were also formed. 5-Hydroxymethylfurfural hydrolysis product was found in the presence of a support without metal. The maximal yield of sorbitol equal to 49% was reached over 3%Ru-HPA/ZrO2 calcinated at 550 °C. |
