The invention discloses a formation method of an Mg/Sn/W composite oxide catalyst. The formation method comprises the following steps: evenly mixing an Mg/Sn/W composite oxide catalyst powder body with a binding agent to obtain a mixture; then adding an extrusion aid, a peptizing agent and a pore-forming agent into the mixture and then mixing again to obtain wet material agglomerates; putting thewet material agglomerates into a strip extruding machine and then extruding the wet material agglomerates into strip-shaped materials to obtain the formed catalyst; drying the formed catalyst in a drying box, and putting the dried catalyst into a muffle furnace and then roasting the dried catalyst at high temperature. According to the formation method of the catalyst, the mechanical strength of the catalyst can be improved in a formation process of the catalyst, active sites of the catalyst cannot be destroyed at the same time, and the reduction of the catalytic activity of the formed catalystcan be avoided. 本发明公开了种Mg
