摘　　要：以C_(17)～C_(20)重蜡脱氢为探针反应,考察反应温度、反应压力、氢烃体积比及空速等工艺参数对Pt-Sn-K/γ-Al_2O_3催化剂脱氢反应性能的影响。结果表明,C_(17)～C_(20)脱氢反应适宜的工艺条件为:反应压力0.14 MPa,氢烃体积比600:1,空速20 h^(-1)和反应温度高于440℃,此条件下,转化率达14%以上。The effects of the operation parameters such as reaction temperature, reaction pressure, H2/ paraffins volume ratios and space velocity on the behavior of Pt-Sn-K/Al2O3 dehydrogenation catalyst was investigated using results showed that the the dehydrogenation of long-chain paraffins conversion of over 14% was attained under （ C17 - C20 ） as the probe reaction. The the optimum condition as follows：reaction pressure 0.14 MPa, H2/paraffins volume ratio 600： 1, space velocity 20 h^- 1 and reaction temperature over 440 ℃.
