摘　　要：开发了高产苯的歧化催化剂,考察了工艺条件对催化剂的影响。结果表明:在反应温度415~420℃,反应压力2.5 MPa,空速2.5~3 h^(-1),氢烃物质的量比为2~3的条件下,甲苯转化率为53%~55%,苯选择性为44%~47%,二甲苯选择性为42%~44%,进行了1000 h小试的稳定性评价,催化剂性能良好,具备应用前景。A disproportionation catalyst with high yield of benzene was developed,and the influence of process conditions on the catalyst was studied.The results showed that under the conditions of reaction temperature 415~420℃,reaction pressure 2.5 MPa,space velocity 2.5~3 h-1,and molar ratio of hydrogen 2~3,the toluene conversion rate was 53%~55%,benzene selectivity was 44%~47%,and the xylene selectivity was 42%~44%.The stability evaluation of 1000 h pilot tests showed that the catalyst had good performance and application prospects.
