| 摘 要： | 采用沉积沉淀法和浸渍法制备了MgF2-AlF3催化剂，应用XRD、NH3-TPD、BET和拉曼光谱等对催化剂进行表征，并将催化剂应用于四氟乙烷裂解制备三氟乙烯反应。结果表明，沉积沉淀法制备的MgF2-AlF3-D具有较高的活性和反应稳定性。反应温度450 ℃时，四氟乙烷转化率为33.4%，三氟乙烯选择性大于99%。催化剂表面酸性和积炭是影响催化剂活性和稳定性的主要因素。

| Abstract: | A series of MgF2-AlF3 catalysts were prepared by deposition precipitation method and impregnation method,and characterized by XRD,NH3-TPD,BET and Raman.The as-prepared catalysts were used in catalytic pyrolysis of tetrafluoroethane(HFC-134a) to trifluoroethylene(TrFE).The results showed that MgF2-AlF3 catalysts prepared by deposition precipitation method exhibited higher activity and stability than those by impregnation method,and tetrafluoroethane conversion of 33.4% and the selectivity to trifluoroethylene of 99.8% were attained at reaction temperature 450 ℃.The strength of surface acid sites and carbon deposit on the catalyst surface were the main influencing factors of the catalyst activity and stability. |
