摘　　要：以硫化态CoMo/γ-Al2O3,NiW/γ-Al2O3,NiMo/γ-Al2O3,NiMoW/γ-Al2O3为催化剂,1-甲基萘为加氢反应的模型化合物,利用高压加氢微型反应器考察在不同类型催化剂体系上1-甲基萘的加氢饱和反应规律。结果表明:对1-甲基萘的芳烃饱和性能,Ni-Mo-W型最优,Ni-Mo型、Ni-W型次之,Co-Mo型最低;催化剂的活性越高则1-甲基萘的芳烃饱和越容易达到热力学平衡,对压力的变化越不敏感;1-甲基萘的加氢饱和优先发生在不带甲基的芳环上,产物中5-甲基四氢萘的质量分数约为1-甲基四氢萘的2倍。Using 1-methylnaphthalene as a model compound and sulfided CoMo/γ-Al2O3,NiW/ γ-Al2O3,NiMo/γ-Al2O3,NiMoW/γ-Al2O3 as catalysts,the hydrogenation saturation performance of 1-methylnaphthalene on the four different catalysts was studied using a high pressure hydrogenation micro-reactor.It is found that the NiMoW/γ-Al2O3catalyst is with the best saturation performance for 1-methylnaphthalene and the CoMo is the lowest.The higher the activity is,the easier the aromatic saturation of 1-methylnaphthalene is to reach the thermodynamic equilibrium and the less sensitive to the change of reaction pressure.In the products the amount of 5-methyl tetralin is about as twice as 1-methyl tetralin.
