  • Patent number: 10927010
    Abstract: A seed crystal is a crystal of zeolite that is to be deposited on a support when producing a zeolite membrane complex that includes the support and a zeolite membrane formed on the support. A volume-cumulative particle size distribution of the seed crystal, measured by a laser diffraction scattering method, has a coefficient of variation of 0.5 or less and a kurtosis of 5 or less. Use of these seed crystals improves the bonding of zeolite crystals when producing the zeolite membrane. As a result, a dense zeolite membrane can be formed.

  • Publication number: 20200384423
    Abstract: Part of a zeolite membrane of a zeolite membrane complex is set in pores of a support over a boundary surface between the zeolite membrane and the support. With respect to a main element constituting the zeolite membrane, a distance in a depth direction perpendicular to the boundary surface between a position at which a ratio (B/C)/A is 0.8 and the boundary surface is preferably not smaller than 0.01 ?m and not larger than 5 ?m. B/C is a value obtained by dividing an atomic percentage B of the main element inside the support by a porosity C of the support. The ratio (B/C)/A is a ratio of the value to an atomic percentage A of the main element in the zeolite membrane.

  • Publication number: 20200306700
    Abstract: A zeolite membrane complex includes a support and a zeolite membrane formed on the support. The zeolite membrane is of an SAT-type zeolite. Among particles on the surface of the zeolite membrane, particles that have aspect ratios higher than or equal to 1.2 and lower than or equal to 10 account for 85% or more of the area of the surface of the zeolite membrane. This improves the orientations of the particles and also reduces the interstices among the particles. As a result, the denseness of the zeolite membrane is improved. Accordingly, for example, high gas separation performance can be obtained when the zeolite membrane complex is used as a gas separation membrane.

  • Patent number: 10770905
    Abstract: While a power storage installation operates as a virtual generator to maintain an power storage amount, a power generating installation calculates a first generated power change rate command value from a deviation between a frequency of a power distribution system and a frequency command value, calculates a second generated power change rate command value from received power measured by a received power measurer, calculates a second active power command value by integrating a generated power change rate command value to which the first generated power change rate command value and the second generated power change rate command value are added, and controls an output of the power generating installation based on the second active power command value.
