    摘要: The present invention concerns Y-type FAU zeolites with hierarchical porosity having an Si/Al atomic ratio strictly greater than 1.4 and less than or equal to 6, having controlled and optimised crystallinity, and having mesoporosity such that the mesoporous outer surface area is between 40 m2·g−1 and 400 m2·g−1. The present invention also concerns the method for preparing said Y-type FAU zeolites with hierarchical porosity.

    摘要: A method for synthesis of porous inorganic materials, preparation of a catalyst and catalytic cracking of petroleum hydrocarbons thereof includes processes for synthesis of porous inorganic materials and preparation of the catalytic cracking catalyst and catalytic cracking of petroleum hydrocarbons. The synthesis process is advantaged in low cost in raw materials; the porous inorganic material has various pore structures; and transitional metal used overcomes the defects of the catalytic properties. The porous inorganic material serving as the main active ingredient and containing crystalline aluminum silicate zeolite structures provides surface acidity required by the catalytic reaction. The surface acidity is flexibly adjusted. The hierarchical pore profile improves the accessibility of the active center of the zeolite structure and favors the reaction efficiency and benefits of the petroleum hydrocarbon cracking, and reduces the negative effects caused by diffusion limit. The catalyst containing the porous inorganic material has low manufacturing cost and better properties.
