Abstract: [cze] [eng]
Anorganické membrány jsou používány zejména pro jejich dobré mechanické vlastnosti, odolnost vůči vysokým teplotám a tlakům a též chemickou stabilitu v agrasivním prostředí (kyseliny, zásady, organická rozpouštědla). Při přípravě anorganických membrán se využívá celá řada nejrůznějších materiálů: oxidy, oxidová keramika, kovy, slitiny, polyméry polyamidy. Připravené porézní elementy byly charakterizovány permeačními metodami, metodou Hg-porozimetrie a SEM. Druhá část je věnována přípravě mikroporézních vrstev na bázi zeolitu MFI na porézních nosičích. Inorganic membranes have been used for separation of various liquid and gas mixtures due to their high mechanical and chemical resistance at elevated temperatures and pressures. The materials such as stainless steel, ceramics, polymers are available for preparation of the inorganic membranes. This paper is focused on the preparation and characterization of the composite membranes consisting of a ceramic support and layer of zeolite. The first part of the paper deals with the preparation of the porous ceramic supports, which are made using dry molding of a ceramic suspension mixed with the organic dispersant. The supports were characterized by permeation of N2, mercury porosimetry and SEM. The second part of the paper is focused on the preparation of microporous zeolite (MFI) layers on the supports. These microporous membranes were characterized by permeation and separation of H2 and iso-butane.
