Relative Permeability Of Coal: A Review Springerlink

Coalbed methane (CBM), once a hazard to the undermining safety, is becoming an important addition to the global energy supply. Injecting carbon dioxide $$(\\hbox {CO}_{2})$$ ( CO 2 ) into coal seams not only aids to enhance CBM production but also offers an option of $$\\hbox {CO}_{2}$$ CO 2 sequestration helpful for the reduction of greenhouse gas release. Multiphase flow occurs in those ...

Cement is produced by feeding into a cement-making zone the residue solids containing carbonaceous material and ash constituents. The residue solids may be obtained from a coal, or like material, conversion process, for example coal pyrolysis or liquefaction. Advantageously, however, the residue solids are obtained from a gasification process of coal or like material.

Coal Production And Prices Decline In 2015

U.S. coal production in 2015 is expected to be about 900 million short tons (MMst), 10% lower than in 2014 and the lowest level since 1986. Regionally, production from the Appalachian Basin has fallen the most. Low natural gas prices, lower international coal demand, and environmental regulations have contributed to declining U.S. coal production.
