摘　　要：介绍了反应原料甲苯与碳九及以上芳烃(C^(+)_(9)A)不同比例对HLD甲苯歧化催化剂反应性能的影响。C^(+)_(9)A与甲苯的比例变化对催化剂的反应性能和产物组成有较大影响,同时对产物中非芳生成量也有一定影响,工业装置可以通过调节原料比例进而调整反应产物中苯和碳八芳烃的组成。The effects of different ratios of toluene and C_(9) and above aromatics on the reaction performance of HLD disproportionation catalysts is introduced.The change of the ratio of C^(+)_(9) aromatics to toluene has a great influence on the reaction performance of the catalyst and the composition of the product.At the same time,it also has a certain influence on the amount of non-aromatic production in the product.In industrial plants,the benzene and carbon eight aromatics in the reaction product can be adjusted through adjustment of the ratio of raw materials.
