ABSTRACT:
A catalyst composition comprising a low acidity, highly dealuminated ultra stable Y zeolite having an Alpha value of less than about 3 and Broensted acidity measured by FT-IR from about 1 to about 20, preferably from about 1-10, micro mole/g of, an amorphous cracking component and a catalytic amount of hydrogenation component selected from the group consisting of a Group VI metal, a Group VIII metal, and mixtures thereof is disclosed. The present invention provides for a process for converting hydrocarbonaceous oils comprising contacting the hydrocarbonaceous oils with the catalyst under suitable hydrocarbon conversion conditions. Such processes in include, but are not limited to, single stage hydrocracking, two-stage hydrocracking, series-flow hydrocracking, mild hydrocracking, lube hydrocracking, hydrotreating, lube hydrofinishing, hydrodesulphurization, hydrodenitrification, catalytic dewaxing and catalytic cracking.
