The thermoplastic development of a coking coal was studied before and after treatment to study the impacts on thermoswelling and volatiles release. The treatment process consisted of two consecutive steps, namely mild pyrolysis and solvent extraction.

Deep coalbed methane (CBM) is widely distributed in China and is mainly commercially exploited in the Qinshui basin. The in situ stress and moisture content are key factors affecting the permeability of CH4containing coal samples. Therefore, considering the coupled effects of compressing and infiltrating on the gas permeability of coal could be more accurate to reveal the CH4 gas seepage ...

Apr 30, 2020 · India has vast coal resources all over the country; however, the presence of high ash content makes them invulnerable for industrial usage. To compensate for the rapid depletion of highquality coking coals and to compensate for the demand for coal in iron and steel sectors, coal cleaning or beneficiation and blending techniques have come into limelight for the usage of lowquality coal.

To improve indirect drying efficiency, the effect of soda residue on the drying characteristics of coking coal were studied using a selfmade indirect drying system. A tube furnace was used in the dry distillation of coal samples with soda residue, and the coke properties were analyzed. The results indied that the soda residue has a significant influence on the increase in the heating rate ...
