Abstract
The invention relates to an improved method for the production of liquid carbon compounds from coal. According to the invention coal is oxidized at 80.degree. to 300.degree. C. in the presence of the vapors of a C.sub.1-5 aliphatic alcohol, optionally under the introduction of steam, and then the liquid carbon compounds are separated from the resulting product mixture. The process according to the invention can also be performed under atmospheric pressure, 50-80% of the carbon content of the coal converted appear in the liquid product. The liquid product contains the more valuable fraction, boiling below 300.degree. C., as major component.
