Title: Method for separating liquid and solid products of liquefaction of coal or like carbonaceous materials

A method of improving the quality of slurry products taken from coal liquefaction reactors comprising subjecting the slurry to treatment with an alkaline compound such as caustic soda in the presence of steam in order to decompose the phenolic and acidic materials present in the slurry, and to also lower the slurry viscosity to allow separation of solid particles by sedimentation.
