摘要

Adsorption of methane from diluted methane/nitrogen mixtures in a fixed bed reactor was experimentally studied and modelled in this work. Three different Metal-Organic Frameworks (MOFs), Basolite C300, F300 and A100 were considered for this purpose, the adsorption bed being operated at 298 K, 0.1 MPa, and an inlet methane concentration of 2%. Methane adsorption capacities decrease in the order: Basolite C300 (0.078 mmol/g) > Basolite F300 (0.040 mmol/g) > Basolite A100 (0.028 mmol/g). In addition, a mechanistic model based on the numerical solution of an heterogeneous one-dimensional model considering axial dispersion has been used for modelling these adsorption results.
