Method for effecting coal-liquefying reaction

摘要

A method of liquefying coal by reaction in a slurry mixture with a solvent consisting of an organic heavy fraction, with the application of heat, is characterized in that the slurry-based reactants are mixed with light aliphatic compounds to make use of the latent and sensible heats of the latter in lowering the reactant temperature, whereby the coal-liquefying reaction and thermal polycondensation reaction of the organic heavy fraction are controlled.
