HY zeolite-ased catalysts for hydrocracking heavy oils

摘要

Hydrocracking of Arabian-Heavy atmospheric residue was carried out over. Y-zeolite supported catalysts. The results indicated that the measoporosity of zeolite played an improtant role in the increase in hydrocracking heavy fractions. In addition, it was found that the distribution of the acid sites and hydrogen supply from the sulfide to the acid sites were the improtant facotrs to maximize the hydrocracking functions of zeolites.
