HYDROTREATING/HYDROCRACKING PROCESS WITH LOW ACIDITY CATALYST

摘要

Conversion of hydrocarbons is conducted over low acidity zeolites such as the sodium form of zeolite ZSM-5 to yield products like those produced by hydrocracking but with substantially decreased proportion of light hydrocarbons having one to four carbon atoms. (Sulfiding of sodium zeolites activates such sodium zeolites for the present purpose.) The hydrocarbon conversion is conducted with mixed-phase charge (Trickle mode) under hydrogen pressure or with liquid-phase charge in a liquid-full reactor.
