Abstract

Several catalysts of composite zeolites were synthesized from (TEA)(2)O-Na2O-Al2O3-SiO2-H2O system adopting different conditions of the preparation The prepared zeolites, in the hydrogen-exchanged form, were characterized by EDS and XRD. The obtained catalysts consisted of beta-zeolite composited with different amounts of other zeolites such as mordenite and/or analcime. Acidic properties of these composite zeoliteswere measured potentiometrically in an aqueous medium. The hydration of butene-1 over the H-exchanged composite zeolites was carried out at250 degrees C and 180 atm, and with a water/olefin ratio of 3.86. Thehydration activity was discussed in terms of structural characteristics and acidic properties of the prepared catalysts.
