Document Type and Number:
WIPO Patent Application WO/2015/016062
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the calorific value, and to obtain coal having further reduced mercury content. The method involves carrying out a drying step (S1) in which coal (1) of low grade is dried to obtain dry coal (2); a dry deashing step (S2) in which the ash component (6) is eliminated from the dry coal (2) obtained in the drying step (S1), by a dry deashing means to obtain deashed dry coal (3); and a carbonization step (S3) in which the deashed dry coal (3) obtained in the dry deashing step (S2) is carbonized to obtain deashed carbonized coal (4).
