ABSTRACT:
The invention includes a method for preparing a crystalline zeolite having the X-ray diffraction lines of Table 1. The method includes preparing a template-free reaction mixture including at least one active source of a first oxide selected from the group consisting of an oxide of silicon, germanium or both, optionally at least one active source of a second oxide selected from the group consisting of an oxide of aluminum, boron, gallium, iron or a mixture thereof; and heating the reaction mixture at crystallization conditions for sufficient time to form a crystallized material containing zeolite crystals having the X-ray diffraction lines of Table 1, where said zeolite crystals have a first oxide/second oxide molar ratio greater than 12.
