摘要：研究了负载型磷钨酸催化剂对乙醇气相脱水制乙烯的催化作用。在固定床反应器上考察了其性能,最佳条件:γ-A l2O3负载8%的磷钨酸,温度240℃,空速0.60 h-1。最佳工艺条件下,乙醇转化率达99.28%,乙烯选择性99.36%。催化剂稳定性好,与传统的液体无机酸相比,具有催化活性高、环境友好和能耗低等优点。
The catalytic behaviors of supported reactor. The optimal reaction condition was as phosphotungstic acid catalyst were studied in a fixed-bed follows： 8% phosphotungstic acid supported on γ-Al2O3, 240 ℃, LHSV 0.60 h^-1. Ethanol conversion of 99.28% and ethylene yield of 99.36% were obtained under the optimal condition. The catalyst is superior to conventional liquid inorganic catalysts, with higher activity, environmental-friendliness, lower energy consumption and good stability.
