Polymer based membrane composites for separation of small molecules

Project goals

Up to recently the development of membranes for separation of gases as well as vapours has been based mostly on homogeneous organic or inorganic layers. The aim of the present project is to examine feasibility of the latest type of composites based oncombinations of polymer-macroporous polymer, polymer-hypercrosslinked polymer, and polymer-carbonized molecular sieve. Microporous sorbents i.e. polymeric sorbents and zeolites will be used as fillers and polyimide, polyisobutylene, poly(phenyleneoxide), poly(methylsiloxane) or an polyepoxide resin were used as binders. Membranes were cast from solution or by polymerization. A porous ? -alumina support would be used to improve the mechanical properties of the heterogeneous membranes. Theheterogeneous membranes will be tested for permeability of H2, O2, N2, methane and permselectivity of mixtures of low molecular hydrocarbons using a Wicke-Kallenbach cell. Determination of parameters, which are necessary for practical application of

    Membrány na bázi polymerních kompozitů pro separaci malých molekul

  • Annotation in Czech

    Doposud byly vyvíjeny membrány pro separaci plynů a par převážně na bázi homogenních organických neb anorganických vrstev. Cílem tohoto projektu je prozkoumat možnosti posledních typů kompozitů založených na kombinacích polymer-makroporézní kopolymer,polymer-hypersíťovaný kopolymer a polymer-karbonizovaná molekulová síta. Mikroporésní sorbenty tj. polymerní sorbenty a zeolity budou užity jako plniva a polyimidy, poly(fenylenoxid), polyisobutylenový kaučuk, poly(methylsiloxan) nebo polyepoxidovápryskyřice budou použity jako pojidla. Membrány budou tvářeny z roztoku neb polymerizací. Porézní ?-alumina bude použita jako podložka pro zlepšení mechanických vlastností heterogenních membrán. Permeabilita H2, O2, N2, methanu heterogenním membránami aselektivita směsí uhlovodíků o nízké molekulové hmotnosti bude testována pomocí Wicke-Kallenbach cely. Membrány budou charakterizovány parametry (difuzní tok, permeabilita, selektivita a difuzní koeficient), které jsou nezbytné pro praktické aplikace
