H_3PO_4-BF_3/ZrO_2及H_3PO_4-BF_3H_2SO_4/ZrO_2催化剂上异丁烷/丁烯的烷基化反应

Alkylation of Isobutane with Butenes on H_3PO_4-BF_3/ZrO_2及H_3PO_4-BF_3H_2SO_4/ZrO_2

研究了H_3PO_4-BF_3/ZrO_2及H_3PO_4-BF_3-H_2SO_4/ZrO_2催化剂对异构烷烃烷基化反应的催化作用。就载体的焙烧温度、活性组分的浓度、BF_3及H_2SO_4的添加及反应温度对催化剂活性的影响进行了较为详尽的研究。

A new type of alkylation catalysts for isobutane with butenes were prepared by ZrO2 impregnated with H3PO4-BF3 or H3PO4-BF3-H2SO4 and dried at lower temperature. The effects of the calcination temperature of ZrO2, the concentration of impregnation solution, the addition of BF3 and H2SO4, and the reaction temperature on the activity of catalysts were researched. Acidity and stability of these catalysts were also discussed.
