Abstract: Method and a system for capturing mercury in a flue gas are provided. The method includes partially oxidizing a carbonaceous solid fuel in a gasifier such that a thermally activated carbon-containing solid sorbent and gaseous gasification products are generated wherein the gasifier is proximate to a combustion system for combusting a mercury containing fuel. The method further includes storing the generated thermally activated carbon-containing solid sorbent proximate to the combustion system and combusting a mercury containing fuel in a combustion zone of the combustion system wherein mercury released during combustion is entrained in flue gas generated by the combustion. The method also includes injecting the thermally activated solid sorbent in the flue gas downstream of the combustion zone and absorbing at least a portion of the entrained mercury on the thermally activated solid sorbent.

Abstract: A method for capturing mercury in a flue gas formed by solid fuel combustion including: combusting coal (12), wherein mercury released during combustion is entrained in flue gas generated by the combustion; generating a thermally activated carbon-containing sorbent by partially gasifying a solid fuel in a gasifier (42) local to the combustion of solid fuel; injecting (26) the thermally activated sorbent in the flue gas, and collecting the injected sorbent in a waste treatment system (28, 34). The gasified gas products may be injected into the combustion of coal. The solid fuel may be coal, biomass, sewage sludge or carbon-containing waste product.
