Abstract RU 2427422 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a catalyst for hydrolysis of cellulose or hydrolysis of cellulose and reduction of products of hydrolysis and a method of producing sugar alcohols from cellulose. Described is a catalyst for hydrolysis of cellulose and hydrolysis of cellulose and reduction of hydrolysis products in which a group 8-11 transition metal is deposited on a solid substrate. Described also is a method of producing sugar alcohols involving: hydrolysis of cellulose in the presence of the catalyst in a hydrogen-containing atmosphere at high pressure and reduction of the product of hydrolysis of cellulose.

EFFECT: easy separation of the catalyst from the product, avoiding the need to regulate pH, neutralise acid or alkali when producing alcohols, possibility of recycling a catalyst without activation thereof, obtaining sugar alcohols directly from cellulose using said catalyst.
