不同催化剂体系上的1-甲基萘加氢饱和反应规律

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。

HYDROGENATION PERFORMANCE OF 1-METHYLNAPHTHALENE ON DIFFERENT CATALYSTS

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-Al2O3 catalyst has 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 as twice as 1-methyl tetralin.
