摘　　要：引入转化率和副反应率的概念,采用气相色谱的外标法,对裂解汽油一段催化剂进行苯乙烯加氢评价。得出了其加氢的最佳工艺条件为:反应温度为50℃,反应压力2．80 MPa,空速8 h-1,氢油比120:1;对比评价YH-30与YH-20催化剂,得出YH-30比YH-20具有较高的选择性和稳定性。Ratio of coversion and ratio of side reaction was applied to value first stage hydrogenation catalyst of pyrolysis gasoline by external standard method of gas chromatography .The optimum process conditions was put forward at the basis of performance test of YH-30 catalyst ,reaction temperature 50 ℃,reaction pressure 2.80 MPa ,airspeed 8 h^-1,hydrogen oil ratio 120：1. YH-30 catalyst has better selectivity and stability than that of YH-20 catalyst.
