| 摘 要： | 考察了加氢裂化催化剂中HY分子筛与金属负载量对其催化1-甲基萘精制油样加氢裂化反应产物的影响。结果表明，在酸性较强的催化剂上甲基四氢萘类反应主要是单分子反应机理，通过异构开环路径生成较大量单环芳烃，同时有一定量BTX化合物生成。HY分子筛质量分数的增加可提高催化剂中中强B酸中心数量，提高四氢萘类异构开环转化成断侧链单环芳烃的选择性；增加催化剂的金属负载量对四氢萘类生成多环烷烃及单环烷烃有利。

| Abstract: | Hydrocracking product yields of prehydrotreated 1-methyl naphthalene were investigated over the catalysts with different HY zeolite mass fractions and metal loadings. The results indicated that methyltetralin was hydrocracked through mono-atom pathway and large yield of mono-cyclic aromatic was detected accompanied by BTX. Middle and strong B acid sites increased with the increase of HY zeolite mass fraction in catalyst, which favored the transformation of tetralins to mono-aromatic with short side-chain. Increasing metal loadings of the catalyst enhanced the yields of mono and di-cyclic cycloalkane in catalytic hydrocracking of prehydrotreated 1-methyl naphthalene. |
