Comparison of gas permeability models for mixed matrix membranes

Comparison of several well-known models for predicting mixed matrix membrane (MMMs) gas permeabilities are discussed. The models that are considered are: Maxwell model, modified Maxwell model, Lewis-Nielsen model, modified Lewis-Nielsen model and Felske model. For comparing the models, experimental...
