Abstract
An economic route to transport fuels from low grade feedstocks containing organic polycyclic components and mineral and/or metallic components comprises separating the feedstock into (a) a residue containing fuel values and substantially all of the mineral and metallic components and (b) a liquid hydrocarbon fraction; hydrogenating the liquid hydrocarbon fraction; providing hydrogen for the hydrogenation by steam reforming methane-containing gas recovered from the hydrogenated material; and providing the heat for the steam reforming by immersing the reformer reactor tubes in a fluidized bed heated by combustion of residue from the separation step. If the fluidized bed is pressurized, the process can be made substantially self-contained with all the heat and power requirements for steam generation and feedstock compression for hydrogenation and steam reforming being recovered from the flue gas.
