Coal liquefaction
Abstract
In a two-stage liquefaction wherein coal, hydrogen and liquefaction solvent are contacted in a first thermal liquefaction zone, followed by recovery of an essentially ash free liquid and a pumpable stream of insoluble material, which includes 850.degree. F.+ liquid, with the essentially ash free liquid then being further upgraded in a second liquefaction zone, the liquefaction solvent for the first stage includes the pumpable stream of insoluble material from the first liquefaction stage, and 850.degree. F.+ liquid from the second liquefaction stage.
