A commercial NaBEA sample was exchanged, at different levels, with NH4+ cations through conventional and microwave promoted methods. The dependence of the acidic and catalytic properties of the HNaBEA samples; with the exchange degree was analyzed. It was observed that the catalytic activity of the exchanged samples for methylcyclohexane cracking depends on the exchange method, whereas surface acidity, determined by pyridine adsorption followed by IR spectroscopy and temperature programmed desorption of NH3, do not.
