Abstract
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. The hydrocarbon conversion is conducted with mixed phase charge (trickle mode) under hydrogen pressure or with liquid phase charge in a liquid-full reactor. The product of such conversion is admixed with a pour point depressant for storage.
