Abstract:
1. A method of decreasing pollutants produced in a combustion process, comprising: introducing oil shale particles into a combustion chamber in the presence of at least one pollutant selected from the group consisting of a nitrogen-containing pollutant, sulfuric acid, sulfur trioxide, carbonyl sulfide, carbon disulfide, chlorine, hydroiodic acid, iodine, hydrofluoric acid, fluorine, hydrobromic acid, bromine, phosphoric acid, phosphorous pentaoxide, elemental mercury, and mercuric chloride; combusting the oil shale particles to produce sorbent particulates and a reductant; exposing the at least one pollutant to at least one of the sorbent particulates and the reductant at a temperature ranging from greater than or equal to approximately 450° C. to less than approximately 1150° C.; and exposing the sorbent particulates to at least one of the mercury and mercuric chloride at a temperature of less than or equal to approximately 200° C.
