| Abstract: | The performance of resin catalyst for sulfur transfer of the alkylation of thiophene sulfides in heavy gasoline was investigated.The change of sulfur distribution before and after reaction was analyzed and the kinetics of the reaction was researched.The results showed that the sulfur transfer rate of alkylation was above 90% under the reaction condition of reaction temperature 110 ℃ and reaction time 60 min.The alkylation of thiophene with olefins was first order reaction,the apparent activation energy was 20.32 kJ·mol-1 and the pre-exponential factor was 1 364 h-1;the kinetics equation of thiophene sulfide alkylation was expressed as follows:r=1364exp（-2.445×103/T)cT. |
