Abstract:
     This invention concerns the continuous process of supercritical gas extraction of coal, the major feature of which is that the problem of process continuation is solved. It consists of pumping system for feeding coal slurry continuously, the continuous supercritical gas extraction equipment, the timed residue removal system under high temp. and pressure, and the continuous recovery and separation system for solvent and fuel oil. The said method can be used for supercritical extraction of fossil fuels such as coal, oil shale, etc.
