本文利用Ｐｔ／ＳＯ＾２－４／ＺｒＯ２，Ｐｔ／ＷＯ３／ＺｒＯ２负载于大比表面Ａｌ２Ｏ３固体强酸催化剂，进行异丁烷和丁烯的烷基化反应。
The alkylation of iso-butane with butene was investigated over Pt/SO2-4 /ZrO2 and Pt/WO3/ ZrO2-Al2O3 catalysts prepared by the authors. Based on the alkylation system with fixed bed reactor, the results showed that the catalysts have high alkylation activity and selectivity for TMPs. Under 150℃ and 5.4MPa, the conversion of butene was 100% and selectivity of 2,2,4-TMP was 83.2% over Pt/WO3/ZrO2-Al2O3catalyst. The GC-MS analysis showed the alkylates condensed by dry ice were contained 65.1 % and 83.2 % 2,2,4-TMP separately at 1. 7h and 6. 8h. The regeneration of deactivated catalysts was studied also. It resulted in that addition of a few amounts of H2 increased the amount of the octane and its isomers, and decreased the amount of polymer by-products.
