摘要:

通过临氢微型反应器中催化剂评价实验，对铂含量0.05％(ω)，镍含量ω分别为0.05％、0.1％、0.2％、0.3％、0.4％、1％、2％的七种Pt-Ni/HBeta催化剂进行了评价，发现裂解率比未引入镍时大，镍的引入量大于0.1％后，选择性、转化率以及异构化率都有所升高并趋于平稳，选择性为4％左右，转化率为80％左右，异构化率为75％左右，说明非贵金属镍的引入有利于异构化反应。

Abstract:

Pt-Ni/HBeta isomerization catalysts have been studied in this paper with a hydro-microreactor, seven Pt-Ni/HBeta catalysts of Pt content 0.05% and different Ni contents as 0.05%,0.1%,0.2%,0.3%, 0.4%,1%,2%were tested respectively. It is found that the
