Patent ID: 8246727

Claim:
A pollution abatement system comprising: a packed bed reactor having an inlet for receiving an effluent stream generated in a combustion source comprising sulfur oxides and carbon dioxide respectively present in the effluent stream at an initial amount and an outlet, the reactor having at least one chamber comprising a plurality of solid particles having an average particle diameter size of about 0.25 mm to about 12 mm, wherein the solid particles comprise a slag component having a silicon dioxide content of greater than or equal to about 25% by weight and having one or more reactive silicate compounds and a binder component, wherein the chamber has a volume corresponding to a sufficient residence time so as to provide a removal efficiency for sulfur oxides of greater than or equal to about 70% as compared to the initial amount of sulfur oxides present in the effluent stream and a removal efficiency for carbon dioxide of greater than or equal to about 20% as compared to an initial amount of carbon dioxide present in the effluent stream.
