Methane adsorption on coals with different coal rank under elevated temperature and pressure
TL;DR: In this paper, the authors investigated the effect of elevated temperature and pressure on methane adsorption on different types (ranking) of coal and their thermal stability, and found that coal types with higher fixed carbon content have a larger magnitude thermal desorption capacity, indicating that raising coal seam temperature while capturing methane is a promising method for obtaining higher coalbed methane recovery rates, reducing greenhouse gas emissions, and improving mining safety.
