Patent ID: 7993616

Claim:
A method of reducing pollution generated by a combustion source, the method comprising: contacting a fluid stream comprising sulfur oxides and carbon dioxide exiting the combustion source with a substantially dry solid material formed by admixing a slag component having one or more reactive silicate compounds with a binder component, wherein the slag comprises silicon dioxide at greater than or equal to about 25% by weight, and prior to the contacting the fluid stream has a temperature of less than about 600° F. (about 316° C.), and wherein the sulfur oxides present in the fluid stream are removed after the contacting to a removal efficiency of greater than or equal to about 70% in comparison to the initial amount of sulfur oxides present in the fluid stream prior to the contacting and the carbon dioxide present in the fluid stream is removed after the contacting to a removal efficiency of greater than or equal to about 20% in comparison to the initial amount of carbon dioxide present in the fluid stream prior to the contacting.
