Abstract
For upgrading heavy slurry oil containing catalyst fines from a catalytic cracking operation, the viscosity of the slurry oil is lowered in a hydrovisbreaking process step. In a preferred embodiment an admixture of the fines containing slurry oil and a metal containing resid oil fraction, resulting from a crude distillation, is passed through the hydrovisbreaker. The hydrovisbreaker effluent is separated into higher and lower boiling fractions with the lower boiling fraction preferably passed through a cracking unit so as to covert the lower boiling fraction to lower molecular weight hydrocarbon products.
