DISPROPORTINATION OF TOLUENE INTO BENZENE AND XYLENES ON H-MORDENITE ZEOLITES WITH VARIOUS SILICATE MODULES
The paper examined an influence of SİO2/AI2O3 molar ratio on catalytic properties of dealuminated mordendes in the reaction of disproportination of toluene into benzene and xylene in the temperature range 300-380°C, V=3.0 час1, H2.'CH=3:1. It revealed that samples of SİO2/AI2O3 = 17-20 molar ratio are notable for the greater activity and selectivity under the explored conditions. As compared with samples of natural mordende, the synthetic mordende exhibits greater activity and selectivity.
