ABSTRACT:
The present invention relates to a process for removing organic sulphur from coal and the material resulting from the treatment of organic sulphur containing coal with the instant process. The subject process includes the step of mixing coal with ethyl alcohol having less than 4% water. The temperature and pressure of the coal and ethyl alcohol mixture is raised to above the critical temperature and pressure of ethyl alcohol. The coal ethyl alcohol mixture is held at moderate temperature and elevated pressure for a period of about 30 minutes or more. The liquid and solids are separated. The resulting coal solids have substantially less organic sulphur contained therein.
