  • Method of liquefaction of carbonaceous materials
    Patent number: 4451351
    Abstract: Hydrocarbon liquids are obtained from carbonaceous materials, such as coal, by contacting the carbonaceous materials with a metal carbonyl or a low valent complex of the transition metals and water gas under alkaline conditions to form a reaction mixture, and then heating the reaction mixture to a sufficient temperature and pressure to obtain the hydrocarbon liquids. In a second embodiment, the carbonaceous materials are solubilized to an unexpectedly high degree by contacting them with solvent/solute systems, such as phenolic recycle solvents containing alkali or alkaline-earth metal constituents.
