摘要
以丝光沸石为主体制备的HAT-096甲苯歧化与烷基转移催化剂,在空速1.7～2.0 h-1、3.0 Mpa、n(氢):n(烃)=6:1条件下实验室评价1 000 h,转化率大于48%、选择性大于94%.该催化剂在210 kt·a-1工业装置上运行9个月后,在空速1.6 h-1下进行72 h标定,平均转化率大于48%,选择性大于95%.该催化剂已运行6年多未进行再生,表明催化剂稳定性能良好,适宜于长周期运行.
HAT-096 catalyst, a catalyst for disproportionation and transalkylation of toluene and C9 aromatics, was tested on lab-scale apparatus under the following condition： WHSV 1.7- 2.0 h^-1, 3.0 MPa, n（hydrogen）： n （hydrocarbons） = 6：1. Conversion and selectivity remained over 48% and 94%, respectively, after 1 000 h of test. A 72-hour examination test was carried out at WHSV 1.6h^- 1 after 9 months of commercial run on a 210 kt· a^-1 plant, with average conversion of 48 % and selectivity of over 95%. The catalyst has been in operation since 1998 without regeneration, which means that it has good activity stability and is suitable for long-term operation.
