Abstract
Methods for hydrogenolysis are described which use a Re-containing multimetallic catalyst for hydrogenolysis of both C—O and C—C bonds. Methods and compositions for reactions of hydrogen over a Re-containing catalyst with compositions containing a 6-carbon sugar, sugar alcohol, or glycerol are described. It has been surprisingly discovered that reaction with hydrogen over a Re-containing multimetallic catalyst resulted in superior conversion and selectivity to desired products such as propylene glycol.
