Abstract：The forming process of Mg/Sn/W composite oxide catalysts was studied. The characteristics of the catalysts were determined by using X-ray diffraction (XRD)，surface detection system (BET) and scanning electron microscopy (SEM). The effects of different binders， content of binder， different pore-forming agent， content of pore-forming agent and calcination temperature in the preparation process were investigated. Thus the optimum conditions of Mg/Sn/W composite oxide catalyst forming process were determined： the content of proper binder pseudoboehmite sol was 15% and the content of proper activated charcoal was 5%. The drying temperature was 80 centigrade， and the baking temperature was 550 centigrade with the baking time of 3 hours. Under this condition the reaction selectivity is 86.57%.
