Abstract
The invention relates to an improved method for the liquid phase oxidation of coal performed with oxygen optionally in the presence of water. According to the invention oxidation is performed in the presence of a cooxidation partner selected from the group of liquid hydrocarbons and oxygen-containing liquid hydrocarbons, and if water is also present, the pH of the homogeneous solution formed from the cooxidation partner and water is maintained at a slightly acidic value. By the method of the invention the formation of carbon dioxide can be suppressed significantly.
