Thiophenic sulfur compounds can be effectively converted by condensation with CD-1 desulfurizing agent catalyzed by Amberlyst-15 acid porous resin. The thiophenes are transformed to compounds with a boiling temperature beyond the gasoline distillation range, and thus the sulfur compounds can conveniently be removed by distillation. The optimum reaction conditions for desulfurization of a model gasoline sample were found to be a temperature of 80℃ a reaction time of 20 minutes, condensation agent-to-oil mass ratio of 1:100, and catalyst-to-oil mass ratio of 1∶10, giving a conversion of thiophene of ~100%. Basic nitrogenous compounds in gasoline had an adverse effect on the catalyst. The condensation desulfurization methods exhibited high sulfur removal efficiency and has promising prospects for practical application. 
