Abstract
A Sm(III) exchanged NaY zeolite prepared from aqueous SmCl3 was modifi ed with various amounts of fluorine using NH4F. These fluorinated zeol ites exhibit enhanced catalytic activity for the dealkylation of cumen e. The evaluation of acid sites by infrared spectroscopy and pyridine adsorption was correlated with fluorine content.
