Abstract
Ethylene glycol is prepared from a carbohydrate source in a process, wherein hydrogen, the carbohydrate source, a liquid diluent and a catalyst system are introduced as reactants into a reaction zone; wherein the catalyst system comprises a tungsten compound and at least one hydrogenolysis metal selected from the groups 8, 9 or 10 of the Periodic Table of the Elements; wherein the diluent that is introduced into the reaction zone comprises an alkylene glycol; and wherein the carbohydrate source is reacted with hydrogen in the presence of the catalyst system to yield an ethylene glycol-containing product.
