The task of this work was to construct the mixed matrix membrane based on polymer that could be used for the treatment of the waste gases. Therefore, high permeability for the carbon dioxide and low permeability for other gases commonly present in the industrial combustion waste gases (nitrogen, oxygen, hydrogen, methane) are essential. Those membranes belong to the group of dense composite membranes, and mechanism for separation is based on the solution-diffusion mechanism. In this paper, feasibility of the application of poly(ethyleneoxid)-copoly(phtalamide) was tested. In order to enchase the permeability of carbon dioxide, three different zeolites were incorporated, and in order to improve compatibility between the inorganic particles and polymer chains, n-tetradecyldimethylamonium bromide (NTAB).was added. Three zeolites were with the 2-dimensional pores (IHW, NSI and TER). The best results in carbon dioxide/hydrogen selectivity were obtained with the membrane constructed with PEBAX 1657 and surface treated zeolites, while the better results concerning selectivity were gained with membranes based on the Polyactive.
