Abstract:
A method for preparing a crystalline zeolite having the X-ray diffraction lines of Table 1, said method comprising:(a) preparing a template-free reaction mixture comprising 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 sufficient water to shape said mixture; and(b) heating said reaction mixture at crystallization conditions and in the absence of an added external liquid phase for sufficient time to form a crystallized material containing zeolite crystals having the X-ray diffraction lines of Table 1, wherein said zeolite crystals have a first oxide/second oxide molar ratio greater than 12.
