Dealuminated Y zeolite with high crystallinity is obtained from NaY zeolite by treatment with oxalic acid in a buffering system. The effect of dealumination conditions on the degree of dealumination and the crystallinity of the reformed zeolite is discussed. A mechanism for the reaction is proposed.
- NaY zeolite,
- oxalic acid,
- dealumination mechanism
