Abstract

This disclosure relates to liquid-full processes for hydroprocessing a light cycle oil (LCO). The processes involve hydrotreatment followed by selective ring opening in the presence of hydrotreating catalyst and selective ring opening catalyst respectively. The selective ring opening catalyst can be either zeolite ring opening catalyst or amorphous ring opening catalyst. In aspects of zeolite ring opening catalyst, the volume ratio of the total amount of the zeolite ring opening catalyst to the total amount of the hydrotreating catalyst is from about 0.2 to about 1.5. In aspects of amorphous ring opening catalyst, the volume ratio of the total amount of the amorphous ring opening catalyst to the total amount of the hydrotreating catalyst is from about 0.2 to about 3.
