Abstract

Official abstract text for this publication.

A catalyst for cellulose hydrolysis and/or the reduction of hydrolysis products, in which a transition metal of group 8 to 11 is supported on a solid support. A method of producing sugar alcohols comprising: hydrolyzing cellulose in the presence of the catalyst in a hydrogen-containing atmosphere with pressurization; and reducing the hydrolysis product of cellulose. Provided are a catalyst for use in the production of sugar alcohols by the hydrolysis and hydrogenation of cellulose that affords easy separation of catalyst and product, and that does not require pH adjustment, acid or alkali neutralization, or activation of the catalyst during reuse, and a method of producing sugar alcohols from cellulose employing this catalyst.

First claim

Opening claim text (preview).

The invention claimed is: 1. In a method comprising cellulose hydrolysis in the presence of a catalyst, the improvement wherein the catalyst comprises (a) a solid support and (b) ruthenium supported on the solid support surface at a dispersion by carbon monoxide adsorption of 0.01 to 0.03. 2. A method of producing a sugar alcohol comprising hydrolyzing cellulose in a hydrogen-containing atmosphere with pressurization in the presence of a catalyst comprising (a)…
