Abstract�� Oxidative desulfurization(ODS) of diesel with hydrogen peroxide using molecular sieves as catalyst has several attractive features,such as low temperature,low pressure and low cost of operation,besides,the catalyst could be recovered.In this paper,mesoporous Ti-MSU was synthesized by using AEO_9 as template,TEOS as Si source and TBOT as Ti source.The characterization of the synthesized Ti-MSU was carried out by FTIR,XRD and BET.ODS of dibenzothiophene(DBT) with H_2O_2 using Ti-MSU as catalyst was analyzed.The effects of Si/Ti molar ratio and reaction conditions on the sulfur removal were investigated.The conversion of DBT could be 58% under optimal condition.
