Abstract

Researchers synthesized Y zeolite with different particle sizes with fines of Fluid Catalytic Cracking (FCC) spent catalyst. They studied the effect of particle size on physicochemical properties of zeolite .  Results showed that zeolites synthesized via in situ crystallization technique exhibited large surface area, high relative crystallinity and high thermal stability.

With a decrease of particle size of zeolite, both total acid density and B acid sites increased while acid L sites decreased. The cracking activity for heavy oil and coke resistance of ultra-fine zeolite catalysts were enhanced. Authors found that the desulfurization capability of superfine zeolite catalyst to be much higher than that of industrial catalyst.
