Abstract: Cage type catalysts, especially zeolites are very significant in hydrocarbon processing reactions like cracking, isomerization, alkylation, etc. These catalysts when obtained using synthetic sources make the synthesis non-economical. Naturally available clays can serve as a host for the synthesis of such catalysts. Kaolin, as the silica and alumina source, is particularly suitable for the preparation of zeolites due to the high quality and low price. The organic templates are usually used to vary the crystal size and impregnate acid sites on the catalyst. N-propyl amine has been chosen as the template for the synthesis processes. Hydrothermal and ultrasonic methods were performed to determine the effectiveness of each. Hydrothermal synthesis was carried out in a Teflon lined hydrothermal reactor at 100?C for various time intervals. Ultrasonic synthesis was carried out in a bath type ultrasonicator at 30 KHz at 40?C for time spans. The morphology of the obtained catalysts was studied by SEM and XRD analyses. The acid sites concentrations of the catalysts were studied by pyridine adsorbed FTIR analysis and the results were compared. Copyright© 2018 VBRI Press.
