ABSTRACT:
Contaminants, such as sulphur, sulphur compounds and other pollutants are removed from fossil fuels. The fossil fuel in a liquid medium, such as crude oil or a coal slurry, is exposed to metallic copper to react the sulphur with copper ions and settle out the resulting copper sulphide. Additional additives are also disclosed.
