Abstract: The result of a new catalyst for C3 fraction liquid phase selective hydrogenation used in 200 kt/a ethylene unit for 24 months is reported in this paper. The catalyst BC-H-30A allows a wide range of operating conditions, with high activity, high selectivity. It can run at a high liquid space velocity for a long regeneration cycle like BC-L-83 catalyst. Moreover, the catalyst is improved in resisting high concentration of inlet methyl acetylene and propadiene and in the ability of controlling outlet methyl acetylene and propadiene concentration.

摘要: 报道了新型碳三选择加氢催化剂在200 kt/a乙烯装置上工业应用24个月的试验结果。工业应用结果表明:BC-H-30A催化剂适用工况范围广,抗波动能力强,催化活性高,选择性好。既有BC-L-83催化剂的高空速、再生周期长等方面的性能,又在催化剂活性、选择性、耐高浓度甲基乙炔和丙二烯入口的能力、控制出口甲基乙炔和丙二烯浓度的能力等方面有显著提升,与同类催化剂相比,处于国际先进水平。两年来,新增利税176.8万元。
