| Abstract: | Solid superacid catalyst SO4(2-)-WO3-ZrO2 was characterized by means of XRD,DTA-TG, and surface area measurement techniques. The dependence of the surface area, SO42- content of the catalyst on calcination temperature was measured. It was found that there is a synergy to a certain degree between SO42- and WO3 with respect to the delay of ZrO2 crystallization, the stabilization of the tetragonal ZrO2 and the enlargement of the surface area of the catalyst. The addition of WO3 is beneficial to the stabilization of SO42- and remarkably increases the stability of SO42- at high temperature. |
