摘　　要：研究了以 β沸石为主体的HAT 0 97B催化剂在催化甲苯和C9芳烃歧化与烷基转移反应中 ,反应空速、温度及原料中C10 芳烃含量对反应性能的影响。结果表明 ,该催化剂在重量空速2 .5h- 1,反应温度 380℃时反应转化率高达 4 7% ,并可使用C10 芳烃含量达 8%的反应原料 ,可综合利用芳烃资源 。The influences of temperature, WHSV and C 10 aromatics content in the feedstock on the catalytic properties of the β zeolite based HAT 097B catalyst in toluene disproportionation and C 9 aromatics transalkylation reactions were investigated. The results showed that the catalyst has a high conversion(47%) under reaction condition of WHSV 2.5h -1 and 380℃, with the feedstock containing as high as 8% C 10 aromatics. The catalyst showed great commercial potential for making full use of aromatic resources.
