FT-IR studies on the effect of olefins on desulfurization of a CeY zeolite
烯烃对CeY分子筛脱硫效果影响的红外光谱研究

FT-IR spectra of different kinds of sulfides adsorbed on CeY zeolite were collected.Based on that,the effect of olefins(with 1-octene,1,5-hexadiene,and cyclohexene as model compounds) in FCC gasoline on the desulfurization performance of CeY were investigated.The results revealed that a ring-opening catalytic reaction occurs after the sulfides are adsorbed.As compared with alkyl thiophenes,benzo thiophenes are more stable.The strong interactions between the double bond in alkenes with the Ce cation in CeY l...
