Latest Patents

Yumiko Katakura holds a patent for a process for producing a zeolite separation membrane. This process involves creating a porous support primarily made of alumina, onto which a zeolite layer is applied. The method includes several key steps: adhering USY zeolite crystals as seed crystals on the support, bringing a reactant liquid containing silicon and aluminum into contact with the support, and heating the liquid to form the zeolite separation membrane basis material. Finally, the basis material is separated from the reactant liquid to yield the final zeolite separation membrane. This innovative process allows for the production of an FAU zeolite separation membrane that effectively separates mixtures of organic solvents and water.
