Abstract: atalytic alkylation of thiophene with laurylene by four kinds of Y zeolite catalyst was evaluated with gasoline as raw material in a small batch reactor. The experimental results show that USY1 molecular sieve shows highest alkylation activity and better selectivity than the other three catalysts. The optimum conditions of catalytic alkylation by USY1 molecular sieve was as follows: the reaction temperature 140 ℃, reaction time 2 h, catalyst to oil ratio 1∶10. Under above conditions, thiophene conversion rate could reach 88.17%, and high activity could be kept after recycling the catalyst 4 times. 
