Peculiarities of Activity Renovation of Zeolite Catalysts Coked in Hexane Cracking
The initial activity of acid zeolites in n-hexane cracking and influence of their regeneration depth on residual activity using the method of discrete-consecutive coke micro oxidation have been investigated. It was found that oxidation by 5-10 pulses of oxygen properly reflects the activity of catalysts based on faujasite and pentasil, while for mordenite which has increased susceptibility to blocking of channels by coke, such quantity of oxygen is not enough.
