Abstract

Faujasit-type zeolites NaX and NaY include a three-dimensional system of micropores with a pore entrance of 0.74 nm. The dealuminated modification of NaY (zeolite DAY) even contains mesopores. NaX and NaY are applied for technical processes like drying of gases and vapors and for the separation of compounds whereas DAY zeolite acts as fluid-cracking catalyst. Beside a storage of suitable molecules in the micro- and mesopores even larger molecules can be absorbed. Such an enlargement occurs only in microscopic structure defects of the individual zeolite crystals as well as in macroscopic cavities of crystal agglomerates.
