Abstract
A method for producing a bio-coal includes the following steps: (a) lowering the moisture content of a fiber residue obtained after oil extraction of oil palm fruit to less than 25%; (b) after step (a), cutting the fiber residue; (c) after step (b), pelletizing the fiber residue into short-fiber pellets; (d) drying the short-fiber pellets to reduce the moisture content of the short-fiber pellets to below 10%; and (e) after step (d), carbonizing the short-fiber pellets at a temperature below 300° C.
