摘　　要：采用共浸法和NH3程序升温氮化制备了负载于氧化铝上的镍钼双金属氮化物催化剂,运用微反—色谱装置分别考察了催化剂中镍钼负载量、镍钼的摩尔比、反应时间在正辛烷异构化过程中对催化剂性能的影响.试验结果表明,在氮化态催化剂的氧化物前体负载量10-14%,Ni Mo摩尔比为0 6-1 0,反应温度为280-300℃时,在辛烷的异构化反应中,催化剂表现了较好的正辛烷异构化性能,对异辛烷的选择性接近了50%.In this paper,nickel/molybdenum two_metal nitride supported on alumina was prepared by coimpregnation and NH_3 temperature programmed reaction(TPR).The effect of loading of metal,Ni/Mo molar ratio and reaction time on isomerization of octane was invesigated by micro_reactor chromutography instrument.The result showed that nickel/molybdenum nitride supported on alumina with 10%-14% oxide precursor loading and Ni/Mo molar ratio 06-10 had better isomerazition activity at 280-300 ℃ in isomerization of octance.The selectiveity for isooctane is near 50%.
