Adsorption study of dealuminated HY zeolites

Research output: Contribution to journalArticle


Pyridine (py) and acetic acid (Ac) adsorption on dealuminated HY zeolites with Al content in the range of 3.9-58 per unit cell (U.C.) was studied at 553 K by a flow-gravimetric technique. The ratio of the number of adsorbed py and Ac molecules to the number of Al atoms was plotted as a function of the Al content. The plot passes through a maximum for py and a minimum for Ac. The extrema are at about 30 Al/U.C.
