| 中文摘要 | catalysts consisting of heteropoly acids (hpas) supported on different silica and mesoporous molecular sieves have been prepared by impregnation and the sol-gel method, respectively, and their catalytic behavior in fixed-bed alkylation of isobutane with butene has been investigated. the activity, selectivity and stability of the supported-hpa catalysts could be correlated with the surface acidity of the catalysts, the structure of supports as well as the time on stream (tos). in the fixed-bed reactor, the acidity of the heteropoly acid is favorable to the formation of dimerization products (c-8(=)); especially, the pore size of supports was seen to have an important effect on activity and product distribution of the catalysts. contrary to the traditional solid-acid catalysts, the supported-hpa catalysts own an excellent stability for alkylation, which makes it possible for these supported catalysts to replace the liquid-acid catalysts used in industry. |
