Abstract:
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.

Claim (Index 1):
A fluidized passivation apparatus for passivating coal char, comprising\n a reaction chamber defining an interior and having a char inlet for receiving coal char into the interior and a char sump for allowing coal char to exit the interior; the reaction chamber further including at least one gas inlet for admitting an oxygen-containing fluidizing gas into the interior, at least one gas outlet for allowing exit of the fluidizing gas from the interior, and a gas recirculation system comprising a source of fluidizing gas, one or more conduits and a pump, the conduits and pump arranged and adapted to recirculate the fluidizing gas from the gas outlet to the gas inlet under conditions to cause a fluidized state in the coal char within the interior of the reaction chamber; at least one heat exchanger embedded within the interior of the reaction chamber, the heat exchanger having a coolant fluid inlet, a coolant fluid outlet and a plurality of contact surfaces for exchanging heat with coal char within the interior; and a humidifier connected to a source of water and adapted for humidifying the coal char.
