Abstract
The present invention relates to a process for producing hydrogenolysis products of polyhydric alcohols with a high selectivity as well as hydrogenolysis catalysts used in the hydrogenolysis reaction. The present invention provides a process for producing a hydrogenolysis product of a polyhydric alcohol which includes the step of reacting the polyhydric alcohol with hydrogen in the presence of a catalyst containing (A) a platinum-supporting heterogeneous catalyst component and (B) at least one catalyst component selected from the group consisting of tungsten components and molybdenum components, or in the presence of a catalyst containing a heterogeneous catalyst component formed by supporting (A') platinum and the above catalyst component (B), on a common carrier; as well as catalysts for hydrogenolysis of polyhydric alcohols.
