Simple suppressing method of thermal runaway in microwave heating of zeolite and its application

摘要

4A, 13X and Na-mordenite (Na-M) reached higher temperatures by the microwave radiation of 5±10 min in then500 W radiation power and were completely damaged. When 5A was added to 4A, 13X or Na-M with ansuitable ratio, the heating temperature of the mixture was suppressed to a desirable range and the mixturenreached the dehydration degree of w85% in 15±20 min. The mixtures irradiated in desirable conditions onlynslightly decreased their absorption ability for water (by v5% per radiation treatment). The proposed methodncould quickly and simply reactivate the zeolites up to a high level with a domestic type microwave oven.
