عنوان انگلیسی Effect Nano of Zeolite 4A Loading on Polymer Membrane to Increase Permeability and Selectivity CO2/N2
چکیده انگلیسی مقاله The separation of CO2 gas is very important to meet environmental standards, this research aims to prepare a membrane that improves the selectivity of CO2 over N2 gas. Polymer (polyether-block amide) has properties that absorb CO2 well. Nano zeolite 4A has tiny pores proportional to the kinetic diameter of CO2. This mineral particle can act as a molecular sieve in the membrane and improve thermal and mechanical stability. By these two materials, Pebax/4A membrane was prepared. The structure of the membranes was evaluated by FESEM, BET, FT-IR, and mechanical strength analyses, and the permeability, selectivity, diffusion coefficient, and solubility coefficient of carbon dioxide were calculated in them. Finally, it was found that by adding 10% by weight of 4A, the selectivity of nanocomposite improved by %28 ​​compared to pure polymer.
