1 The preferential selection coefficient of CO2 for CH4 under different conditions was characterized by the absolute adsorption capacity (V abs) ratio of CO2 to CH4 (alphaCO2/CH4). Methane aconitase 2 Homo sapiens

3 The Langmuir model fits the adsorption curves of 80 and 100 C better, while the BET model is appropriate for 30 and 55 C. The adsorption affinity of CO2 is higher than CH4, with the value of alphaCO2/CH4 in the range of 2.47-12.16. Methane aconitase 2 Homo sapiens
