- Аннотация: The skeletal isomerization of supercritical n-pentane on the H form of mordenite under flow conditions was studied for the first time. It was found that the conversion of supercritical n-pentane was 30-35% at 90% selectivity for isopentane at 260 degrees C, 130 atm, and a liquid hourly space velocity of 30 h(-1). The catalyst was deactivated as the temperature was increased above 280 degrees C. According to differential thermal analysis data, the deactivation was related to the deposition of condensation products on the surface. The resistance of the H form of the zeolite to poisoning in n-pentane isomerization in a gas phase at 1-8 atm was lower than that under supercritical conditions. It was found that H-mordenite deactivated under gas-phase reaction conditions at 260 degrees C and 8 atm can be regenerated by passing to supercritical isomerization conditions (260 degrees C and 130 atm).
