Gas permeation properties of the matrimid based carbon tubular membrane: the effect of carbonization temperature
Carbon membranes produced from the carbonization of polymeric materials is a promising candidate for gas separation, as it offers good permeability-selectivity combination exceeding polymeric membranes. Carbon membranes are particularly useful in gas separation, and excellent separation could be ach...
