A new binder in production of water-resistant briquettes from bituminous coals: Co-polymer binder

Briquetting could be a solution to economic and environmental problems regarding fine coals. However, briquettes that are formed using molasses disintegrate in water and create problems. Providing water resistance to briquette, bitumen and asphalt are illegally used, however they generate more air pollution. In order to resolve this negative situation, a new binder with a co-polymer origin, Mowilith-VDM^©, is tested for briquetting of bituminous fine coals. The results of tests have shown that class I type (TSE, 1996) water resistance briquette can be produced using the co-polymer binder percent of 8, a drying temperature of 100°C, a drying time of 15 min, and a pressure load of 29.5 MPa.
