  • Patent number: 10294180
    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 ruthenium as hydrogenolysis metal and further at least one promoter metal, selected from transition and post-transition metals; wherein the carbohydrate source is reacted with hydrogen in the presence of the catalyst system to yield a product mixture comprising ethylene glycol and butylene glycol. Butylene glycol may selectively be removed from the product mixture by azeotropic distillation using an entraining agent.
