Abstract: A multi-stage catalytic process for the direct liquefaction of coal is utilized with a hydrotreater to first liquefy and subsequently treat the product in one integrated process. A fresh hydrogenation catalyst is used to reduce heteroatoms (S, N) from coal liquids in the downstream hydrotreater. This catalyst is then cascaded and re-used in the direct coal liquefaction process, first in the low temperature Stage 1, and then re-used in the high temperature Stage 2. Coal liquid products have very low contaminants and can be readily used to produce gasoline and diesel fuel. Catalyst requirements are substantially lowered utilizing this novel process.

Abstract: The invention described herein relates to a novel process for reducing the carbon dioxide emissions from a coal and/or biomass liquefaction facility by utilizing a steam methane reformer unit in the complex designed to produce additional hydrogen which can be thereafter utilized in the process, as required for the plant fired heaters (including the SMR furnace), and for the production of plant steam. The plant light ends (C1, C2, etc.), which are normally utilized as fuel gas streams are the primary feeds to the SMR Unit along with the tail gas purge from a gasification complex within the facility.
