摘要

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 3000C.
