Biogas Upgrading by Transition Metal Carbides [PDF]

ACS Applied Energy Materials, 2017
The separation of carbon dioxide (CO2) from methane (CH4) is critical in biogas upgrading, requiring materials with high selectivity toward one of the two gas components. Hereby we show, by means of density functional theory based calculations including dispersive forces description, the distinct interaction of CO2 and CH4 with the most stable (001 ...
