摘要: 以介孔分子筛SBA灢15为载体,铌酸为铌源,采用浸渍法制备Nb灢SBA灢15催化剂。以质量分数为
30%的H2O2 为氧化剂,Nb灢SBA灢15为催化剂,N,N灢二甲基甲酰胺(DMF)为萃取剂对催化裂化汽油进行了脱硫实
验。结果表明:在温度60曟、反应时间60min、催化剂用量为FCC汽油质量的5%、氧化剂与含硫化合物物质的量
比为3暶1、萃取剂与FCC汽油的体积比为1.0时,催化裂化汽油的脱硫率可达到95.4%,收率为83.8%。

关键词: Nb-SBA-15 , 催化氧化 , 脱硫

Abstract: Niobium Modified SBA15 was synthesized by the wetness impregnation with niobic acid as precursor. The desulfurization of FCC gasoline was carried out with the mass fraction of 30% H2O2 as the oxidant, NbSBA15 as the catalyst, and N, Ndimethyl formamide(DMF) as the extractant. The sulfur removal rate and yield of FCC gasoline can reach 95.4% and 83.8% under the following conditions: reaction temperature: 60 ℃, reaction time: 60 min, weight ratio of catalyst/FCC gasoline: 5%, mole. ratio of oxidant/sulphur compounds 3∶1, and volume ratio of solvent (DMF) to oil was 10.

Key words: NbSBA15 , Catalytic oxidation ,  Desulfurization
