Abstract

Polycationic zeolites were prepared from the H (NH//4)-Y, FAU zeolite. The change of Bronsted acid sites was followed as a function of the pretreating temperature by infrared spectroscopy for mixed (La, Ce) zeolites. It was stated that the 3630 cm** minus **1 absorption band can be related to the acidic OH-groups responsible for the catalytic activity in the alkylating reaction of isobutane with 1-butene, while the band at 3510 cm** minus **1 is characteristic of the non-acidic hydroxyl-groups and has no relation to the catalytic activity.
