STUDY ON SELECTIVE HDS CATALYST MODIFIED BY Ti FOR FCC GASOLINE

Abstract

Abstract: Ti modified alumina carriers were prepared with metatitanic acid and aluminium hydroxide dry powder. CoMo/Al2O3-TiO2 catalysts with different Ti content and different ligands were made by isometric immersion method respectively, and were characterized by XRD, BET, TPR and HRTEM techniques. The selective hydrodesulfurization activities of the catalysts were evaluated in a 10mL fixed-bed micro-reactor. The results showed that the catalyst having 10% TiO2 in carrier and using glycol modifier has higher HDS activity and selectivity.

Key words: selective hydrodesulfurization, FCC gasoline, titanium oxide, glycol
