ABSTRACT:
A zeolite, its method of preparation and use is disclosed. The zeolite is characterized by a silica to alumina mole ratio greater than 12 and a Constraint Index of 1 to 12. The zeolite undergoes controlled alumina extraction by treatment with, e.g., strong mineral acid or chelating agent. Removal of aluminum increases the acid activity of the zeolite.
