CATALYST FOR HYDROLYSIS OF CELLULOSE AND/OR REDUCTION OF HYDROLYSIS PRODUCT THEREOF, AND METHOD FOR PRODUCING SUGAR ALCOHOL FROM CELLULOSE

摘要

Disclosed is a catalyst for hydrolysis of a cellulose and/or reduction of a hydrolysis product thereof, wherein a group 8-11 transition metal is supported by a solid carrier. Also disclosed is a method for producing a sugar alcohol comprising a process for hydrolyzing a cellulose and then reducing the hydrolysis product of the cellulose in the presence of the catalyst in a hydrogen-containing atmosphere under pressure. Specifically disclosed is a catalyst for a sugar alcohol production through hydrolysis-hydrogenation of a cellulose, which catalyst is easily separated from the product and does not require pH adjustment, neutralization of acid/alkali nor activation of the catalyst at the time of reuse. Also specifically disclosed is a method for producing a sugar alcohol from a cellulose by using such a catalyst.
