摘要： In this presentation, the selective oxidation of thiophene in coking benzene with TS-1/H2O2 was studied. The effect of reaction temperature and H2O2/Thiophene molar ratio were systematically investigated. Besides, oxidation products, regeneration times and physicochemical properties of catalysts were studied. Results show that, under the conditions of reaction temperature of 343K and the ratio of H2O2/thiophene>1:4, the removal percentage of sulfur in cocking benzene can reach 98% within 6h’s reaction.
