ABSTRACT:
A method for removal of selected substances from carbonaceous material by use of a solvent is provided comprising: (a) introducing the carbonaceous material containing the selected substances into an extraction zone to form a bed; (b) introducing a gas which at a given pressure liquifies at a higher temperature than the solvent, the introduction being made under a pressure and at a temperature to cause the temperature and pressure of the extraction zone to be sufficient to cause the solvent to liquify when the solvent is introduced to the extraction zone; (c) introducing into the extraction zone the solvent capable of extracting the selected substance; (d) passing the solvent through the bed of carbonaceous material to extract the substances from the material; (e) removing the resulting substance/solvent mixture from the extraction zone to a separation zone under conditions which will maintain the solvent in liquid form as it is passed through the bed of carbonaceous material and out of the extraction zone to the separation zone; and (f) separating the solvent from the substances in the separation zone.
