CATALYTIC CRACKING OF HYDROCARBONS WITH A MIXTURE OF ZEOLITE L AND ZEOLITE Y

摘要

Hydrocarbons, particularly gas oil, are cracked to products boiling in the motor fuel range by using a catalyst mixture comprising zeolite Y and zeolite L. The catalyst of this invention fuel having an increased octane number and suffering a smaller penalty with regard to yield relative to other octane additive systems.
