System and Method for Solid Catalyst Separation In Slurry Reactors

Abstract:

A system and method for processing a treated feed slurry produced by a slurry reactor. The method and system include mixing a chemical separation feed with the treated feed slurry produced by the slurry reactor to chemically separate solid catalyst particles in the treated feed slurry by dissolving the solid catalyst particles using an acid or base in the chemical separation feed. A heavy oil upgrading process that includes the system and method is also described.
