... Abstract The efficiency of the enhanced-coalbed-methane (ECBM) and CO 2 sequestration process depends on the wettability behavior of the coal-water-CO 2 system. It depends on the CO 2 diffusion rate from the cleat network, through the micro-cleats, to the surface of the coal matrix...

... Abstract A new method of coalbed methane (CBM) recovery is proposed wherein hot carbon dioxide at or near supercritical condition is injected into a CBM reservoir to take advantage of enhanced desorption of methane at elevated temperatures and the preferential adsorption of CO 2 on coal...

... methane resources are very rich in China, its resources ranks the third in the world. The coal structure of coalbed methane reservoirs are very complicated, experimental results show that methane content is not the same between low coal rank and high coal rank, therefore, desorption and absorption laws...

... process, capable of enhancing the yield of coalbed methane (CBM) in producing reservoirs. CO2 is preferentially adsorbed onto the microporous structure of coal seams and it displaces the methane molecule from the adsorption sites, thereby enhancing the production of the low carbon eco-friendly fuel...
