Abstract
Polyhydroxylated compounds such as glucose, sucrose, sorbitol, etc. are subjected to a hydrogenolysis reaction at hydrogenolysis conditions which include a temperature in the range of from about 175.degree. to about 250.degree. C. and a pressure in the range of from about 10 to about 2000 pounds per square inch in the presence of a catalytic composition of matter. The catalyst comprises a carbonaceous pyropolymer possessing recurring units containing at least carbon and hydrogen atoms which is impregnated with a transition metal. The products which are obtained will include alcohols, acids, ketones, ethers, and hydrocarbons.
