The composite loading of a new series of catalysts for selective HDS of FCC gasoline has demonstrated excellent desulfurization activity and selectivity and can under conventional hydrotreating conditions manufacture clean gasoline product meeting the national IV emission standard and the Euro V emission standard with less loss in antiknock index. The finalized new series of FCC catalysts upon being adopted for selective HDS of FCC naphtha have good adaptability to different feedstocks along with good stability.展开更多

Furthermore, this paper investigates the oxidative desulfurization selectivity and reaction efficiency when Ce4+ compound and H2O2 having identical electron equivalent weight were used as oxidants. The test re- sults showed that the two kinds of oxidants were more effective to remove benzothiophene in the model oil samples. For oxidative desulfurization of 2-methylthiophene, Ce4+ compound was obviously superior than H2O2. This paper by means of quantum chemistry analyses elaborates the complex formed between Ce4+ species and 2-methylthiophene and FT-IR spec- trograms of model oil samples before and after oxidation by Ce4+ compound and H2O2, respectively. The results demonstrat- ed that Ce4+ compound could remove sulfur compounds not only through oxidation reaction but also through complexation reaction.展开更多
