摘要

the application describes the way to obtain u0441u0430u0445u0430u0440u043eu0441u043fu0438u0440u0442u043eu0432 with five to six carbon atoms with a high output of u0446u0435u043bu043bu044eu043bu043eu0437u043eu0441u043eu0434u0435u0440u0436u0430u0449u0438u0445 materials.at the first stage u0446u0435u043bu043bu044eu043bu043eu0437u043eu0441u043eu0434u0435u0440u0436u0430u0449u0438u0435 source materials (e.g., microcrystalline cellulose and alpha cellulose, wood and u0446u0435u043bu043bu044eu043bu043eu0437u043eu0441u043eu0434u0435u0440u0436u0430u0449u0438u0435 residues, the among both bagasse or wood shavings) are in close contact with the acid by means of a liquid or gaseous phase impregnation or impregnating it u0441u0443u0431u0441u0442u0440u0430 tov.then the treated with acid and dried raw materials in the second stage are treated by exposure to mechanical energy, resulting in the u043bu043bu044eu043bu043eu0437u043eu0441u043eu0434u0435u0440u0436u0430u0449u0438u0435 materials decompose to water soluble products.after that, at the third stage of the water soluble products in the water solution by u0433u0438u0434u0440u043eu043bu0438u0442u0438u0447u0435u0441u043au043eu0433u043e u0433u0438u0434u0440u0438u0440u043eu0432u0430u043du0438u044f, carried out in the presence of u043cu0435u0442u0430u043bu043bu0441u043eu0434u0435u0440u0436u0430u0449 catalyst under pressure of hydrogen with high selectivity and high post are u0441u0430u0445u0430u0440u043eu0441u043fu0438u0440u0442u044b with five to six carbon atoms.
