Patent ID: 7981835

Claim:
A system for the coproduction of activated carbon and boiler-produced steam, the system comprising: a boiler in which a solid fuel from a solid fuel source is thermally converted via combustion with air to produce boiler-produced steam and flue gas, the boiler comprising a boiler-produced steam outlet and at least one flue gas outlet; an activated carbon production apparatus, the activated carbon production apparatus comprising a carbonization zone in which a carbonaceous material is carbonized to produce carbonization gases and char, the carbonization zone comprising carbonaceous material inlet, a char outlet and a carbonization gas outlet; and an activation zone in which char is activated with activation steam to produce activated carbon and activation gases, the activation zone comprising an activated carbon outlet, an activation gas outlet, and an activation steam inlet; and piping connecting the solid fuel source to the carbonaceous material inlet, whereby a portion of the solid fuel source may be introduced into the carbonaceous material inlet.
