摘要：

Properties of solid acid catalysts prepared by modification of oxides have been examined. The oxides Al2O3, SiO2, TiO2, SnO2, Sb2O3, ZrO2 and ZrSiO4 were impregnated by aqueous solutions of H2SO4, H3PO4, NH4F and NH4Cl, respectively, and calcined at 500, 650 and 800-degrees-C. For the so prepared catalysts, the strength and number of their acid centres and their activity for hydrocarbon reactions were determined.
