(54) Process for treating heavy petroleum oil resids


(57) Disclosed is a process for treating heavy petroleum oil resids to produce high yields of useful oil products therefrom. The process comprises thermally cracking the heavy petroleum oil resids under conditions more severethan visbreaking but less severe than delayed coking while simultaneously subjecting said thermally cracking oil resids to steam stripping to separate and recover cracked gases and light oil vapors. The thermally-cracked heavy fluid resid recovered from the thermal cracking step then is subjected to solvent extraction under temperature and pressure conditions in proximity of the critical point of the solvent to separate and recover heavy metal containing asphaltene-containing fractions and low metal oil products therefrom. ,
