Bioconversion of coal: new insights from a core flooding study

Multi scale characterization of coal structure for mass transport

“…Conversion of coal to methane provides a way to reduce the green house gas emissions and other environmental impacts related to coal burning such as SOx emissions (leading to acid rain), particulate matter emission, and heavy metal emission [1]. Coal can be converted into methane by either thermogenic or biogenic conversion.…”

Molecular simulation of CO2/CH4/H2O competitive adsorption and diffusion in brown coal

“…In recent years coalbed methane (CBM) has attracted enormous attention as a high efficient, environmentally friendly and abundant source of energy. [1][2][3] CBM, which consists of methane, a small amount of heavy hydrocarbons, CO 2 , H 2 O, and other gases, is mainly absorbed on the matrix of coal particle surface. The optimal estimation of worldwide CBM resource would exceed 200 trillion cubic meters (Tcm), as much as convectional natural gas.…”

The occurrence state of moisture in coal and its influence model on pore seepage

“…As well, it can avoid the greenhouse effect caused by the emission of gas into the atmosphere. [7][8][9][10][11][12] Coal-seam seepage properties have a vital inuence on the occurrence state, migration and extraction of coal-bed methane, coal and gas outburst, gas explosion, and so on. 13,14 Therefore, researches on seepage characteristic are of signicance to coalseam gas extraction and mine-gas disaster management.…”
