Abstract
The basic experimental researches were carried out for coal liquefaction by solvolysis. The studied items include hydrogenation conditions for treating the primary liquefied products, asphalt, pitch and model solvents (e.g., anthracene oil) in the presence of a commercial catalyst, solvolysis conditions for finely divided, molten coal using a hydrogenation recycled solvent, hydrotreating solvents, analysis of solvolysis-liquefied products, and liquefaction capacity of fractionated solvents for finely divided, molten coal. The studied items for separation of minerals include settlement at high temperature of the solid residue from the first liquefaction stage, and changed coal particle size distribution as a result of the first-stage liquefaction reactions in the presence of a hydrogenation solvent. The experimental study results indicate that conversion of finely divided molten coal into asphaltenes and preasphaltenes is notably accelerated in the phase-II coal liquefaction process by solvolysis, when a hydrotreating solvent is used for the first stage solvolysis process.
