Patent ID: 7960594

Claim:
A method of preparing ethylene glycol from cellulose, which comprises the steps of: providing said cellulose as a raw reacting material; catalytically hydrogenating said cellulose with water in a sealed and high pressure reactor; wherein a catalyst, which is added for catalyzing said cellulose, comprises two sorts of active components, ascribed to a first active group and a second active group, wherein a first active component of said first active group is one or more metals selected from the group consisting of iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium, and platinum of the group 8, 9, or 10 transition metals, wherein a second active component of the second active group is one or more materials selected from the group consisting of metallic state molybdenum, metallic state tungsten, molybdenum carbides, molybdenum nitrides, molybdenum phosphides, tungsten carbides, tungsten nitrides, and tungsten phosphides; and stirring said cellulose within said sealed and high pressure reactor, wherein a hydrogen gas within said reactor at room temperature has an initial pressure in the range of 1 to 12 MPa, wherein a reacting temperature is in the range of 120 to 300° C., wherein a reacting time is equal or longer than 5 minutes; wherein a weight ratio of said second active component of said second active group to said first active component of said first active group is in the range of 0.02 to 1600.
