OCCLUSION AND STORAGE OF KRYPTON IN SOLIDS
The modification process in order to change in a controlled way the effective pore size of zeolites was optimized by investigating the reaction conditions such as degree of chemisorption, reaction temperature, extent of primary - secondary reactions, type of modifying agent, type of substrate, etc. Different reaction and adsorption conditions have been tested to increase the thermal stability of encapsulated krypton in modified zeolites. The possibilities for zeolite modification have been enlarged by combining boranation and silanation with a thermal treatment of sepiolite, and by the formation of boron - nitrogen compounds in zeolites. Screening experiments, on a semi-industrial scale, of the krypton removal from air were carried out. Two kinds of Kr - air separation have been tested successfully on modified mordenite.
