COAL CHAR PASSIVATION PROCESS AND APPARATUS

A continuous process and apparatus for treating dried coal and coal char to promote passivation of the reactive carbon particles by forming a protective oxide coating and simultaneously adding moisture to rehydrate said particles. The passivation process is conducted in a novel apparatus providing for the staged control of the reaction temperature and the staged introduction of both oxygen and moisture. The fluidized bed apparatus has internal in-bed cooling means embedded within the fluidized coal or coal char particles so as to remove the heat energy as it is released by virtue of the exothermic passivation reactions.

THREE-STAGE ENERGY-INTEGRATED PRODUCT GAS GENERATION SYSTEM

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.
