摘要: Methods for synthesizing a nano-sized zeolite beta are described. The method may include mixing alumina and tetraethylammonium hydroxide to form an aluminum solution; mixing silica, additional TEAOH, and water to form a silica slurry; and adding the aluminum solution into the silica slurry and mixing to form an aluminosilicate gel. The method may further include transferring the aluminosilicate gel to an autoclave operated at 120° C. to 160° C. for 2 to 4 days at a rotational speed of 60 to 100 rotations per minute to form a zeolite precursor colloid; washing the zeolite precursor colloid with water to form a washed colloid; drying the washed colloid at 80° C. to 150° C. for 6 to 24 hours to form a zeolite precursor; and calcining the zeolite precursor at 400° C. to 650° C. for 2 to 8 hours to form the nano-sized zeolite beta.

摘要: A composition can include a Rho zeolite with a RHO topology having a Si to B ratio or a Si to Al ratio greater than or equal to 8. Making such a composition can include heating an aqueous reaction mixture having a molar ratio of atomic Si to atomic B of about 4 to about 50 or a molar ratio of atomic Si to atomic Al of about 4 to about 50 in the presence of a C4-C6 diquat of N,2-dimethylbenzimidazole structure directing agent to a temperature of at least 75° C. to produce a Rho zeolite.

摘要: A ZSM-23 zeolite and a process for preparing the same and use thereof are provided. The total acid amount of the ZSM-23 zeolite is 0.05-0.25 mmol/g, preferably 0.06-0.22 mmol/g, more preferably 0.06-0.20 mmol/g. The strong acid content of the ZSM-23 zeolite is 5-33%, preferably 7-33%, more preferably 9-33%, or further preferably 7-31%, further more preferably 10-28% of the total acid amount. The strong acid refers to an acid having a desorption temperature of 350° C. or higher in an NH3 temperature programmed desorption (NH3-TPD). The ZSM-23 zeolite has a low strong acid content.

摘要: The present invention relates to a method of controlling a defect structure in a chabazite (CHA) zeolite membrane, the CHA zeolite membrane having a controlled defect structure by the method and a method of separating CO2, H2, or He and water from a mixture of water and an organic solvent using the CHA zeolite membrane, and more particularly, to a method of controlling a defect structure in a CHA zeolite membrane that improves the separation performance by reducing the amount and size of defects formed in the CHA membrane structure when removing organic-structure-directing agents in the membrane through calcination at a low temperature using ozone.

摘要: The present invention is directed to a method of preparing a synthetic crystalline material, designated as JMZ-12, with a framework built up by the disorder AEI and CHA structures, substantially free of framework phosphorous and prepared preferably in the absence of halides such as fluoride ions. Such method comprises the step of heating a reaction mixture under crystallization conditions for a sufficient period to form a disordered zeolite having both CHA and AEI topologies, wherein the reaction mixture comprises at least one source of aluminum, at least one source of silicon, a source of alkaline or alkaline-earth cations, and a structure directing agent containing at least one source of quaternary ammonium cations and at least one source of alkyl-substituted piperidinium cations in a molar ratio of 0.20 to about 1.4. The resulting zeolites are useful as catalysts, particularly when used in combination with exchanged transition metal(s) and, optionally, rare earth metal(s).
