茚满对HAT-097甲苯歧化与烷基转移催化剂反应性能的影响

Effects of Indan on Performance of HAT-097 Catalyst for Toluene Disproportionation and Transalkylation

为提高重芳烃的利用率,研究了芳烃原料中茚满含量对HAT-097甲苯歧化与烷基转移工业催化剂催化反应性能的影响,并探讨了茚满的反应途径。结果表明:HAT-097催化剂具有较好的抗茚满能力,但随进料中茚满含量的增加,要达到相同的转化率,需提高反应温度;茚满可能发生了5元环的断裂反应,生成了甲乙苯等反应产物。

In order toimprove the use ratio of heavy aromatics, the effects of indan（IND） content in feedstock on HAT-097 toluene disproportionation and C9＋A aromatics transalkylation catalyst were investigated. The results showed that HAT-097 catalyst had excellent performance to cope with IND, but with the increase of IND content in feedstock, the conversion of toluene and C9＋A decreased. In order to keep the same total conversion, the reaction temperature should be increased. Maybe IND was converted into the other products such methyl ethyl benzene（MEB） through 5-member-ring breaking reaction.
