Abstract: Mesoporous X and A zeolites and methods for production thereof are disclosed herein. Such mesoporous zeolites can be prepared by contacting an initial zeolite with an acid in conjunction with a mesopore forming agent. The initial zeolite can have a framework silicon-to-aluminum content in the range of from about 1 to about 2.5. Additionally, such mesoporous zeolites can have a total 20 to 135 ? diameter mesopore volume of at least 0.05 cc/g.

Abstract: Compositions and methods for introducing mesoporosity into inorganic materials in the presence of a non-ionic surfactant are disclosed herein. Mesopores can be introduced into inorganic materials, such as zeolites, by treating the inorganic materials with a non-ionic surfactant. The resulting mesoporous inorganic materials can have a total 20 to 135 ? diameter mesopore volume of at least 0.05 cc/g and a crystalline content of at least 20 weight percent as measured by X-ray diffraction.

Abstract: Compositions and methods for introducing mesoporosity into zeolitic materials employing sequential acid, surfactant, and base treatments are disclosed herein. Mesopores can be introduced into zeolitic materials, such as zeolites, by treatment with an acid and surfactant followed by treatment with a base. The resulting mesoporous zeolitic materials can have a total 20 to 135 ? diameter mesopore volume of at least 0.05 cc/g. Additionally, the resulting mesoporous zeolitic materials can have a total 0 to 20 ? micropore volume of at least 0.10 cc/g.
