Document Type and Number:
WIPO Patent Application WO/2019/027198
Kind Code:
A3
Abstract:
The present invention relates to a coal briquette composition comprising pulverized coal and a binder, the coal briquette composition being characterized in that the binder comprises a cellulose ether that is not gelled at 50-97°C and raw starch, to a coal briquette comprising the coal briquette composition, and to a manufacturing method therefor. According to the present invention, the cellulose ether is not thermally gelled during a gelatinization procedure of the raw starch, requiring a high-temperature condition, and thus a manufacturing step of mixing the binder and the pulverized coal in a high-temperature condition, followed by molding, can be carried out, ultimately leading to a coal briquette having excellent drop strength and compressive strength.
