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