摘要
本文首次将活性组分磷引入了正己烷异构化非贵金属Ｎｉ－Ｍｏ／ＨＺＳＭ－５催化剂上，采用高压微反－色谱装 置分别考察了Ｎｉ／ＨＺＳＭ－５、Ｎｉ－Ｍｏ／ＨＺＳＭ－５、Ｎｉ－Ｍｏ－Ｐ／ＨＺＳＭ－５催化剂的异构化性能。在空速为２ｈ－１，氢烃摩尔比 为８．０，压力为１．５ＭＰａ，反应温度为２３０℃的条件下，当Ｎｉ含量为１．０％、Ｍｏ含量为２．０％、Ｐ含量为１．５％时， 催化剂的异构化收率、选择性和转化率分别高达３１．９％，５７．８％，５５．1％。
In this paper, active component P is loaded over the non-noble isomerization catalyst Ni-Mo/HZSM-5 at the first time. The catalytic poprties of Ni/HZSM-5. Ni-Mo/HZSM-5. Ni-Mo-P/HZSM-5 for the n-hexane are re- searched on continuous microreactor- chromatograph unit. Under the conditions of 230℃, 1. 5 MPa, space velocity 2.0h-l, and H２/n Ｃ６ molar ratio 8 .0, with the optimum catalyst contents of Ni、 Mo and P being 1 .0% 、 2.0% and 1. 5% respectively, the isomerization yield is up to 31 .9%, with selectivity 57. 8% and conversion 55. 1 %.
