摘　　要：在小型固定床评价装置上考察了反应温度、反应压力、氢烃摩尔比及空速对SKI-400H型二乙苯异构化催化剂性能的影响,并对其工业应用过程中工艺参数的调整方案进行了研究。结果表明:在其它条件不变的情况下,随着反应温度或反应压力的提高及氢烃摩尔比或空速的降低,催化剂活性提高,选择性降低;逐步提高反应温度或逐步提高反应压力均可使催化剂活性在一定时间内保持稳定,但提高反应温度,催化剂的选择性明显降低,而提高反应压力对催化剂选择性影响较小。The effect of reaction temperature, pressure, hydrogen/hydrocarbon mole ratio and weight hourly space velocity （WHSV） on the SKI-400H catalyst performance was investigated in a fixed bed. Based on the results, the adjustment of process parameters of its industrial application was conduc- ted. The results show that the catalyst activity is increased with increasing the reaction temperature or pressure or decreasing the hydrogen/hydrocarbon mole ratio and WHSV and the reverse is true for selec- tivity. Gradually increasing the reaction temperature or pressure can keep the catalyst activity stable in a certain period of operation, but higher temperature can make the selectivity of the catalyst decrease sig- nificantly. However, there is a little impact on the selectivity of the catalyst when reaction pressure in- creases.
