Reactor system and solid fuel composite therefor

Abstract

A reactor system includes a fluidized-bed. A fuel and a sulfur absorbent material are eluted through the fluidized-bed. The reactor system may include a heat exchanger having a heat-exchanging portion within a heating zone of the reactor that is hermetically sealed from the heating zone. The reactor may include loose particles of an inert bed material for forming the fluidized-bed. A feed system may be provided to inject a solid fuel composite that includes a mixture of a solid, carbonaceous fuel and a solid reagent into the reactor.
