摘　　要：提出了一种原创性的脱硫方法——缩合法,用于脱除汽油中的硫化物。缩合法利用噻吩类硫化物和硫醇类硫化物和甲醛的缩合反应,将汽油中的硫化物转化为沸点超出汽油馏程的产品,再通过蒸馏的方法除去。在反应温度80℃、反应压力0.1 MPa、进料空速1.0 h-1、剂油比1∶200的最佳工艺条件下,FCC汽油中硫化物的转化率为61.87%。An original method for desulfurization from gasoline, condensation method, is proposecl m tins stuay. Sulfides in gasoline are transformed into products with boiling points exceeding the distillation range of gasoline by condensation reaction of thiophene-type sulfide and methanal, and mercaptan-type sulfide and methanal, which are then removed by distillation method. The conversion rate of sulfide in gasoline is 61.87% under the following conditions ：80% of reaction temperature ,0. 1 MPa of reaction pressure, 1.0 h -1 of feed space velocity and l ： 200 of solvent-oil ratio.
