ABSTRACT:
Coke and metals are removed from a carbo-metallic oil by contacting the carbo-metallic oil in a riser reaction zone with a relatively inert particulate sorbent material in the presence of steam and the resulting coked particulate sorbent material is regenerated in a regeneration zone in the presence of steam and oxygen to remove the carbonaceous deposits by means of oxidation, water gas reaction and carbon gasification. The operating conditions in the riser reaction zone and the regeneration zone are regulated to provide a maximum coke level on the regenerated particulate sorbent of about 0.25 wt. %.
