Abstract
According to one or more embodiments disclosed herein, a mesoporous zeolite may be made by a method comprising contacting an initial zeolite material with ammonium hexafluorosilicate to modify the framework of the initial zeolite material, and forming mesopores in the framework-modified zeolite material. The contacting may form a framework-modified zeolite material. The mesoporous zeolites may be incorporated into catalysts.
Claims20
A method for making a mesoporous zeolite, the method comprising:
- contacting an initial zeolite material with ammonium hexafluorosilicate in water to modify the framework of the initial zeolite material, forming a framework-modified zeolite material, the initial zeolite material comprising silica and alumina, and comprising an FAU framework type structure;
- and
- forming mesopores in the framework-modified zeolite material.
A method of making a catalyst, the method comprising:
- forming a mesoporous zeolite by a method comprising:
- contacting an initial zeolite material with ammonium hexafluorosilicate in water to modify the framework of the initial zeolite material, forming a framework-modified zeolite material, the initial zeolite material comprising silica and alumina, and comprising an FAU framework type structure;
- and
- forming mesopores in the framework-modified zeolite material to form a mesoporous zeolite;
- and
- incorporating the mesoporous zeolite with a metal oxide support material and one or more metal catalyst materials to form the catalyst.
