Abstract
Effects of ultrasonic irradiation on the catalytic performance of PtSnNa/ZSM-5 catalyst for propane dehydrogenation were studied. XRD, TEM and TPDA were used to characterize the catalysts. From the results of XRD, the structure of ZSM-5 was not destroyed by the ultrasound. Ultrasound promoted the dispersion of Pt on the surface of the carrier during impregnation and decreased the size of Pt particles. Compared with the catalyst prepared by conventional impregnation, the supported catalyst prepared by ultrasonic irradiation showed better catalytic activity in propane dehydrogenation.
