Glucose and cellobiose were used as the model feedstocks to probe the influence factors for the conversion cellulose to ethylene glycol(EG).For glucose and cellobiose hydrogenolysis under hydrogen atmosphere in the presence of Ni-WO3 catalyst,EG yield showed different dependence on reaction temperature; the optimum reaction temperature for glucose was lower than that for the cellobiose.Additionally,both glucose and cellobiose had their own optimum W-Ni ratio,and the ratio of W to Ni for glucose was a slight lower than that of cellobiose due to the higher reactivity of glucose.
