| Summary: | 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. [Projekat Ministarstva nauke Republike Srbnije, br. TR 34011 i
