Abstract

Abstract: Zn, La, Zr, Sn and Ti loaded molecular sieves were prepared by impregnation method.
Conversions of benzothiophene and dibenzothiophene over the metal oxides modified ultra
stable zeolite Y(USY), ZSM-5, β and MSU-2 molecular sieve catalysts were investigated by
means of micro-activity test (MAT) experiments. The results showed that Zn and La loaded
catalysts were better than the other metals, and ZSM-5 with lower SiO2/Al2O3 mole ratio
showed better results than those with higher SiO2/Al2O3 as far as desulfurization reaction
is considered. A comparison of the desulfurization activities of the La/Zn-USY catalyst
with USY catalyst indicated that the bimetal loaded USY catalyst gave good products
selectivity when sulfur containing heavy oil was used as the feedstock. The sulfur content
in gasoline fraction was decreased by 25%, and there was no loss in the Research Octane
Number.

Key words: desulfurization, catalytic cracking, metal oxide, zeolite, hydrocarbons
