Abstract: The invention provides a method for synthesizing a mesoporous zeolite ETS-10 containing a metal without a templating agent. The method according to the invention comprises the steps of: mixing a silicon source with a NaOH solution to obtain a mixed solution so that the content of Na2O in the mixed solution is 10.0% to 20.0% by weight; adding a KOH or KF solution so that the content of K2O is 10.0% to 25.0% by weight and stirring it well; adding a titanium source solution and stirring it well; adding a precursor compound containing metal Ni and/or Co and stirring it well; and subjecting it to a crystallization reaction to obtain the mesoporous zeolite ETS-10. The mesoporous zeolite ETS-10 obtained by the invention has a specific surface area of 320 to 420 m2/g, a mesoporous volume of 0.11 to 0.21 cm3/g, and thus can be used as a catalyst and a support thereof in synthesis industry for macromolecular fine chemicals.

Abstract: A method of making and using a new family of crystalline microporous metalloalumino(gallo)phosphosilicate molecular sieves is disclosed. These molecular sieves have been synthesized and are designated high charge density (HCD) MeAPSOs. These metalloalumino(gallo)phosphosilicates are represented by the empirical formula of: Rp+rA+mM2+wExPSiyOz where A is an alkali metal such as potassium, R is at least one quaternary ammonium cation such as ethyltrimethylammonium, M is a divalent metal such as Zn and E is a trivalent framework element such as aluminum or gallium. This family of metalloalumino(gallo)phosphosilicate materials is stabilized by combinations of alkali and quaternary ammonium cations, enabling unique, high charge density compositions. The HCD MeAPSO family of materials have catalytic properties for carrying out various hydrocarbon conversion processes and separation properties for separating at least one component.

Abstract: Hierarchically porous ZSM-5 zeolites, having macropores, mesopores, and micropores are formed using a solid-state crystallization process. An aluminosilicate nanogel prepared with precursors, solvent, and a structure-directing agent is provided. The solvent is evaporated from the aluminosilicate nanogel at room temperature. The dried aluminosilicate nanogel is then heated to promote crystallization. The crystallized zeolites are calcined to remove the structure-directing agent.
Abstract: Disclosed is a method for readily and inexpensively producing zeolite without using an organic structure-directing agent (organic SDA). Specifically disclosed is a method whereby a gel containing a silica source, an alumina source, an alkaline source and water is reacted with zeolite seed crystals, to produce a zeolite with the same kind of skeletal structure as the zeolite. The gel used is a gel of a composition whereby, when a zeolite is synthesized from this gel only, the synthesized zeolite comprises at least one of the kinds of composite building units of the target zeolite.
