Experimental measurements of carbon dioxide, methane and nitrogen high-pressure adsorption properties onto Malaysian coals under various conditions

In this study, the CO2 adsorption capacity was measured on Malaysian sub-bituminous coals in dry and moisture equilibrated state using volumetric technique to understand its carbon sequestration and storage potential. The CO2 adsorption capacity onto dry and wet coal samples was performed at 300�3...
