Effect of nanoparticle loading on the polymer surface (Polyether-block-amide) in CO۲/CH۴ selectivity

In this research, we want to separate carbon dioxide gas from methane gas. Polymer (poly-ether-block-amide) has properties that absorb carbon dioxide well. Zeolite ۴ A nanoparticles have fine pores and are proportional to the kinetic diameter of carbon dioxide, so they can act as a molecular sieve in the membrane, this nanoparticle was added to the polymer to obtain Pebax/۴A nanocomposite membrane. Nanoparticles can improve carbon dioxide emissions and the thermal and mechanical stability of membranes. In this research, we want to investigate the effect of nano zeolite loading on the permeability and selectivity of carbon dioxide. By adding nanoparticles to the polymer, its structure was changed, so the nanocomposite membrane was evaluated by FESEM, BET, FTIR, and analyses. Finally, permeability, selectivity, diffusion coefficient, and solubility coefficient of carbon dioxide were calculated.
