چکیده:

Polyurethane was synthesized by using two steps polymerization from toluene diisocyanate(TDI), polypropylene glycol(PPG) and 1,4-butanediamine (BDA). In order to improve gas separation performance of polymeric membranes, micro powder of zeolite was incorporated to them. Mixed matrix membranes (MMMs), consisting of polyurethane/zeolite 3A0 was successfully fabricated by thermal phase inversion method. The prepared MMMs were exposed to O2, CO2, N2, and CH4 gases to determine the permeability and selectivity of PU/3A0 zeolite membranes. The gas permeation experiment was designed by design expert software. The performance of the mixed matrix membranes (PU/3A0 zeolite) was studied as a function of zeolite loading and different operating conditions including pressure and temperature. Zeolite contents of 6, 12, 18, 24 wt% was employed. The obtained results showed that increasing zeolite content caused increasing gas permeabilities of O2, N2, CH4, and CO2.
