Abstract
PURPOSE: To enable a coal to be subjected to liquefaction under ordinary or slightly increased pressures by using as a solvent a modified pitch obtained by such treatment of a coal- or petroleum-pitch as hydrogenation or alkylation.
CONSTITUTION: The objective coal liquefaction can be accomplished by mixing a coal with a modified pitch which can be obtained by hydrogenation or alkylation of a coal pitch containing poly (≥4) nuclear aromatics (e.g. a soft pitch, hard pitch), or a cracked residue and vacuum-distilled residue of a petroleum (e.g., a naphtha tar pitch, ethylene tar pitch, still residue), followed by carrying out a heat-treatment at 300W500°C under ordinary or slightly increased pressures.
