Abstract

The catalytic cracking of n-pentane over sodium, cerium and aluminium exchanged Y zeolites and H-ZSM-5 zeolite has been studied. A promoting action of oxygen at 693–753 K on the catalytic activity has been found to follow the order: CeY>AlNaY>NaY>H-ZSM-5. It is suggested that oxygen adsorbed on the CeY zeolite takes part in reactions with Ce3+ ions.

Abstract

Изучены каталитиеские свйства цеолитов NaY, CeY, AlNaY, HZSM5 в реакции пиролиза н-пентана в интервале температур 693–823 К. Найдено, что влияние кослорода на каталитическую активность исследованных цеолитов уменьшается в ряду: CeY>AlNaY>NaY>H-ZSM5. Предложен вероятный механизм действия кислорода в реакции пиролиза н-путана.
