ABSTRACT:
An energy efficient process for beneficiating and dewatering high water content carbonaceous materials utilizing a pneumatic stream to entrain, transport, dewater and to carbonize organic carbonaceous material in a fluidized bed. The process utilizes physical separation for principal removal of moisture and reduces contact between organic carbonaceous matter and hot process water, thereby retaining a high organic content in the product fuel. The organic carbonaceous materials are chemically beneficiated during carbonization in a fluidized bed contactor. Heat exchange and heat recovery procedures provide an economical, energy efficient process.
