Abstract
Vacuum residue is used for production of olefins by first separating, preferably by solvent extraction, the asphalt therein, blending resultant asphalt depleted fraction with a lighter fraction, e.g., a vacuum gas oil, and then subjecting the blend to a conventional catalytic hydrogenation step prior to thermal cracking. The hydrogenate may be separated into fractions with the heavy fraction only being thermally cracked.
