| Abstract: | Dealundnated Y zeolite with high crystallinity is obtained from Ner 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. |
