  • Patent number: 10737982
    Abstract: The monolithic base is a porous alumina body that includes pores and that is configured by alumina particles as an aggregate and an oxide phase as a binding material. The alumina particles include microscopic alumina particles having a particle diameter of greater than or equal to 0.5 ?m and less than or equal to 5 ?m and coarse alumina particles having a particle diameter of greater than 5 ?m. The number of microscopic alumina particles that are encapsulated in the oxide phase is greater than or equal to 50% of the total number of microscopic alumina particles and coarse alumina particles.

  • Publication number: 20200197879
    Abstract: A zeolite membrane complex comprises: a support; and a zeolite membrane formed on the support. The membrane is of SAT-type zeolite, and in an X-ray diffraction pattern obtained by X-ray irradiation to the zeolite membrane, a peak intensity around 2?=13.9° is 1.5 times or more a peak intensity around 2?=8.5°.

  • Publication number: 20200030753
    Abstract: A peak intensity of a (110) plane is greater than or equal to 2.5 times a peak intensity of a (004) plane in an X-ray diffraction pattern obtained by irradiation of X-rays to a membrane surface of the AFX membrane.

  • Publication number: 20200009512
    Abstract: A peak intensity of a (002) plane is greater than or equal to 0.5 times a peak intensity of a (100) plane in an X-ray diffraction pattern obtained by irradiation of X-rays to a membrane surface of the ERI membrane.

  • Publication number: 20190292062
    Abstract: Seed crystals are crystals of zeolite to be attached onto a support in production of a zeolite membrane complex including the support and a zeolite membrane formed on the support. The specific surface area of the seed crystals is not smaller than 10 m2/g and not larger than 150 m2/g. The strength obtained from a crystal component at a diffraction angle 2? indicating a maximum peak in a range of diffraction angle 2? from 12° to 25° in an X-ray diffraction pattern obtained by emitting X-ray to the seed crystals is not less than once and not more than 30 times that obtained from an amorphous component. It is thereby possible to improve adherence of the seed crystals to the support.
