Abstract

Notwithstanding manifold works devoted to the receiving of granulated zeolite-containing sorbing materials, controversial data exists regarding the types utilized binding agents as well as the conditions under which the composite materials are made with the appropriate firm and sorbing characteristics. The experimental data is conveyed concerning the elaboration of technology of receiving zeolite ceramic adsorbents with modified inorganic binding on the basis of highly flexible clay and synthetic zeolites NaA and NaX. Using standardized methods in ceramic technology to control structural physical and physico-mechanical parameters, the optimum conditions of modification of binding agent and its correlation with the zeolite component have been determined which allow to get the adsorbent with the proper parameters of firmness, sorbing capacity and porosity. According to the data of electronic microscopy of the composites of optimum composition the following has been specified: their structure belongs to the corpuscular type and represented by the individual crystals and units of zeolite phase which are linked between each other with the help of fragments of porosities clay binding. The results of low temperature adsorption of nitrogen indicate that the formation while smelting highly porous materials with the highly specific area and predominance of pores of the two groups of denomination: micropores and macropores. Hence, received materials thanks to the obvious sorbing properties and inherent to the zeolite phase of molecule sieve effect, can be used in the range of selective adsorbing processes, such as division of carbohydrate mixtures, deeply drying of gases and others.
