以镍为催化剂的加、脱氢活性组分，钼为助催化组分，丝光沸石为载体，制备了Ｎｉ－Ｍｏ－ＨＭ双非贵金属催化剂，用於正戊烷的异构化反应。考察了催化剂的残钠量，镍、钼含量，以及反应条件对正戊烷异构化反应的影响。应用正交法设计试验，在最佳反应温度３００℃、压力２．０ＭＰａ、空速１．０ｈ－１和氢烃摩尔比４．０的条件下，正戊烷转化率为６７．５％；异构烷选择性９５．５％；≥Ｃ５异构烷产率６３．８％；≥Ｃ５液收率９４．５％。在１００ｍｌ装置上连续反应１０００ｈ，催化剂的性能稳定。
Ni-Mo-HM double non-noble metal catalysts were prepared for the isomerization of n-pentane using nickel as catalyst, dehydrogenation active component, molybdenum as cocatalyst and mordenite as carrier. The effects of reaction conditions on n-pentane isomerization reaction were investigated. Orthogonal design method was used to test the conversion of n-pentane to 67.5% under the optimal reaction temperature of 300 ℃, pressure of 2.0 MPa, space velocity of 1.0 h-1 and molar ratio of hydrogen to hydrogen of 4.0. Isoparose selectivity 95.5%; ≥ C5 isoparaffin yield 63.8%; ≥ C5 liquid yield 94.5%. Continuous reaction in 100ml device 1000h, the catalyst performance and stability.
