Kinetics of Gas Phase CO2 Adsorption on Bituminous Coal from a Shallow Coal Seam [PDF]
Energy & Fuels, 2022 This article examines the CO2 adsorption–desorption kinetics of bituminous coal under low pressure injection (0.5 MPa) in the context of CO2 sequestration in shallow level coal seams. This study used two different sizes of intact core samples of bituminous samples from seam no. 30 at the Experimental Mine Barbara (EMB) in Katowice, Poland.
