Abstract

The effect of hydrothermal treatment of decationized superhigh-silica zeolite on the mechanism of n-hexane conversion has been studied. It has been established that thermosteam modification sharply decreases the cracking activity and increases the selectivity to aromatization reactions. Zeolite acidity markedly decreases, but its crystal structure does not become amorphous.

Abstract

Изучено влияние термопаровой обработки декатионированной формы сверывысококремнеземного цеолита на закономерности превращения н-гексана. Термоларовое модифицирование приводит к резкому падению крекирующей активности и повышению селективности в реакциях ароматизации. При этом наблюдается значительное снижение кислотности цеолита без заметной аморфизации кристаллической структуры.
