Heterogeneous membranes based on zeolites for separation of small molecules
Heterogeneous zeolite-based membranes with polymeric binder were tested for the separation of hydrogen and methane. The separation process was characterized by parameters such as permeability, selectivity, and diffusion flux. The prepared membranes are superior to homogeneous polymeric membranes in permeability and diffusion flux. For B,ICH, separation selectivity equal to 10 was attained.
