摘要：

Supported Cesium Acid Salts of 12-tungstophric acid exhibit very high activities as catalysts for various reactions, because of their superacidity, high surface area and insolubility in water and polar solvents[1,2]. In this work, supported Cesium acid salts are prepared by first impregnating the aqueous solution of Cesium Carbonate onto SiO2, followed by drying and calcining, then impregnating the aqueous solution of H3PW12O40, followed by drying and calcining. The etherification of Light FCC Gasoline with methanol was conducted in a Fixed-bed reactor. Products were analyzed by GC.
