Abstract

H-forms of faujasite, clinoptilolite and mordenite were obtained from NH//4-forms in the desorption of NH//3 by increasing the temperature. The water loss of H-zeolites resulted in their dehydroxylated forms. All these processes were registered by TG (thermogravimetric) and DTA curves. On the basis of X-ray studies and adsorption capacities, structure changes could be followed in connection with dehydroxylation. Rehydration of the dehydroxylated species was attempted at 25, 180 and 400 degree C. No gravimetrically detectable rehydroxylation can be observed while some restoration of the catalytic activities in n-butene isomerization and in the cleavage of C-C bonds in paraffinic hydrocarbons point to a certain extent of reversibility of dehydroxylation.
