From the study. we found that pure silicon fanjasite showed different thermal behaviors below 1500K and above 1500K. its cell volume gradually shrinks with the rising of the temperature below 1500K. the cell volume of the zeolite changes little above 1500K.展开更多
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.展开更多
