ZOC-120 applies to FCC unit of the vacuum gas oil. It has excellent selectivity, good hydrothermal stability, great coke selectivity and strong ability to maximize the total liquid yield, etc. It can be used to raise the production of gasoline or diesel according to users’ demand.
1. Active Component Technology
1) Secondary synthesis of NaY zeolite: Long crystallization time, unique variable temperature crystallization synthesis, high silica to alumina ratio, high stability, intact crystal structure.
2) NaY zeolite modification: High retain of crystallinity, less non-framework aluminum, smooth pore channels, and perfect dispersion of Re3+.
2. Matrix Processing Technology
1) Special treatment on Kaolin: increase the surface area and pore volume; form mesoporous structure with certain activity and microporous structure with high aluminum content; appropriate matrix activity to enhance bottom cracking reaction.
2) Colloidal active alumina technique: increase the surface area and pore volume; macroporous structure is conducive to the proliferation of reactant molecules and product molecules; improve acidity and distribution of acid sites and enhance cracking activity.
