Abstract
A FCC catalyst, CHV-1, with high vanadium tolerance was developed for processing high vanadium content resid feedstock. The basic research indicated that cerium oxide deposited on the surface of the Y zeolite could react with vanadium to avoid destruction of the zeolite structure by vanadium. CHV-1 was formulated with SRY and RPSA zeolites as active components and mesopore alumina as matrix. The commercial results indicated that CHV-1 in comparison with the original catalyst for processing high CCR and vanadium content feedstock, CHV-1 decreased coke and slurry yields by 0.23 wt% and 3.58 wt% respectively; increased LPG plus naphtha plus LCO yield by 3.42 wt% and naphtha RON by 1.8; and the catalyst makeup rate lessened by 0.4 kg/t.
