Bio-Char Respectively Bio-Coke from Agricultural Wastes for Metallurgical Uses

T. Griessacher, J. Antrekowitsch & D. Offenthaler
Bio-char and bio-coke production units are typically low and medium temperature working processes, which generate a product with average quality normally used as fuel, intermediate for active carbon or soil fertilizer. If now the carbonization or pyrolysis process is run at higher temperatures and at the absence of air, the production of high quality bio-coke is possible, which meets the special requirements of most metallurgical processes and therefore makes the substitution of fossil coal and...
