Abstract

Abstract
Cu(I)Y, NiY and CeY zeolites were prepared by liquid phase ion exchange and characterized by means of XRD, ICP/MS and N₂ physisorption. Properties of selective adsorptive desulfurization of FCC gasoline on the adsorbents have been investigated by fixed-bed adsorption experiment and GC-SCD technique, especially the removal selectivity of the sulfur compounds in the oils. The results indicated that the removal selectivities of the sulfur compounds in the gasoline were quite discrepant for different adsorbents, among which, CeY had the sequence of 2-ethyl-5-methylthiophene
3 mercaptan
2-thiophene<2 or 3-methylthiophene
3 mercaptan<2-ethyl-5-methylthiophene2-thiophene<2 or 3-methylthiophene
Keywords:
