摘要： A method for reducing the emissions from combustion gases produced during a combustion process includes injecting a hydrocarbon-based reducing agent into the combustion gases to form a combustion gas mixture. The combustion gas mixture including oxides of nitrogen, NOx, is directed through a selective catalyst reduction (SCR) system including a catalyst bed to remove NOx from the combustion gas mixture and to produce an exhaust gas. In one embodiment, the exhaust gases are released from the SCR to the atmosphere.

摘要： A method of operating a gasification facility includes injecting a carbonaceous material into a gasification reactor. The method also includes converting at least a portion of the carbonaceous material into a solid waste byproduct that includes residual carbon. The method further includes reactivating at least a portion of the residual carbon. The method also includes injecting at least a portion of the reactivated carbon into the gasification reactor.
