Abstract
This invention provides an improved process for deriving liquid fuels from coal which involves the steps of (1) solubilizing coal in a FCC residual oil to form a solvated coal solution phase and an ash solids phase; (2) subject the two phase admixtureto FCC conversion conditions; (3) separating and recovering a hydrocarbon phase and a catalyst-ash solids phase in a catalyst-ash solids phase; (4) treating the catalyst-ash solids phase in a catalyst regeneration zone, and removing entrained ash solids from the flue gas effluent of the catalyst regeneration zone; and (5) fractioning the hydrocarbon phase to recover liquid fuel products.
