To provide a high-quality wood-based coke usable as a heat source and a carbon material (a recarburizer) in nonferrous metal/steel manufacture by carbonizing a wood-based industrial waste such as ogalite (artificial firewood made from sawdust) as a carbonaceous material; and to provide a method for producing the wood-based coke.
The method for producing the wood-based coke comprises (a) a step for obtaining a molded product by subjecting a dried and finely powdered carbonaceous material to compression molding, and (b) a step for carbonizing the molded product at a temperature within a range of 400-800°C while intercepting the entrance of air. The obtained wood-based coke has ≥90 wt.% (preferably ≥92 wt.%) fixed carbon and ≥0.4 g/cm3 bulk specific gravity.
