ABSTRACT:
A method for enhancing solubilizing mass transport of reactive agents into and out of carbonaceous materials, such as coal. Solubility parameters of mass transfer and solvent media are matched to individual peaks in the solubility parameter spectrum of coals to enhance swelling and/or dissolution.
Methanol containing reactive agent carriers are found particularly effective for removing organic sulfur from coals by chlorinolysis.
