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