ABSTRACT:
A process for demetallation and desulfurization of resids by visbreaking an admixture of resids, particulate solids, and steam and/or hydrogen, and then subjecting the visbroken mixture to high temperature settling and separating to provide a first vapor product, a liquid product, and a recycled underflow solids stream. The process further comprises coking the liquid product to produce a second vapor product and coke and then distilling the combined first and second vapor products to yield a plurality of demetallized and desulfurized liquid hydrocarbon products. A fraction of the recycled underflow from the settler/separator is removed as a purge stream and burned for recovery of heat and metals. If hydrogen is used in the visbreaking step, the first vapor product is condensed to separate the hydrogen for recycling.
