摘　　要：制备了Pt/Sn/HZSM-5催化剂,进行了床层温度、系统压力以及进料空速对丙烷脱氢制反应转化率的影响试验,还针对该反应建立了丙烷转化率对床层温度、系统压力以及进料空速等相对变量的关系式,并根据实验数据优化部分参数,以最终得到的转化率关系式对实验数据进一步拟合,拟合结果十分理想,平均偏差仅为2.61%,表明该转化率关系式拟合精度高,适用性强。A Pt/Sn/ZSM-5 catalyst was prepared, and the effect of reaction temperature, system pressure and space velocity on the conversion of propane in the catalytic reaction of propane dehydrogenation to propylene over it was investigated. A conversion equation for propane dehydrogenation to propylene was given and its parameters was optimized by using the experimental data. The equation obtained had high fitting precision for the experimental data with an average deviation of only 2.61%, which indicated that the proposed equation was reasonable.
