A dehydration method is a dehydration method for selectively separating water from a mixture that contains water, and the method includes a step of supplying the mixture to a supply side space of a zeolite membrane having an ERI structure, and a step of making a pressure difference between the supply side space and a permeation side space of the zeolite membrane having an ERI structure.

The present invention relates to a process for producing a porous support-zeolite membrane composite, which comprises forming a CHA type zeolite membrane on a porous support by a hydrothermal synthesis in the presence of seed crystals, wherein an FAU type zeolite is used as the seed crystals.

Disclosed are selectively-permeable membranes and components configured for selective permeation of a specified gas, such as oxygen, therethrough, methods for making the same and methods for using the same, for example, to implement fuel cells and electrochemical cells.

This invention discloses a thin-film composite thin-film composite membrane that is useful for the separation of solute species in organic solvents and particularly in aggressive, high boiling-point, polar-aprotic solvents such as dimethylsulfoxide, (DMSO), N-Methyl-2-pyrrolidone (NMP), dimethylacetamide (DMAc), dimethylformamide (DMF). Thin-film composite separation performance and durability is greatly enhanced through electrostatic crosslinking of an ionomer selective layer by incorporation of a multi-valent counter-ion. The thin-film composite is resistant to contact with amines and the separation efficiency is tunable by choice of multi-valent counter-ion or through the applied pressure differential across the membrane.

Stable and economical methods for producing coenzyme Q10A are described. These methods include concentrating a culture suspension of a coenzyme Q10-producing microorganism efficiently, while minimizing a loss of coenzyme Q10 prior to an extraction step or a homogenization process. The methods for producing coenzyme Q10 may comprise a filtration step of passing a culture suspension of a coenzyme Q10-producing microorganism through a porous membrane in a state where the culture suspension is heated to a heating temperature of 35° C. or higher. In order to improve the average permeation flux, a regenerating step may be performed, preferably at least once, which involves closing a filtration device, applying pressure, and then releasing the pressure; or a regeneration treatment of allowing a medium to flow in from a filtrate outlet side and passing the medium through the porous membrane for a certain time, prior to normal filtration.

A catalytic membrane reactor and methods of operating and producing the same are provided that efficiently produces highly pure hydrogen (H.sub.2) from ammonia (NH.sub.3) as well as operates according to other chemical conversion processes. In one embodiment, a tubular ceramic support made from porous yttria-stabilized zirconia has an outer surface that is impregnated with a metal catalyst such as ruthenium and then plated with a hydrogen permeable membrane such as palladium. An inner surface of the ceramic support is impregnated with cesium to promote conversion of ammonia to hydrogen and nitrogen (N.sub.2). The resulting catalytic membrane reactor produces highly pure hydrogen at low temperatures and with less catalytic loading. Therefore, ammonia can be used to effectively transport hydrogen for use in, for example, fuel cells in a vehicle.

In one instance, the first molecules may include CO.sub.2 molecules. In another instance, the second molecules may include H.sub.2O molecules. In one or more embodiments, the zeolite material may be a DDR-type zeolite material. For example, the DDR-type zeolite material may be applied on a porous α-alumina substrate.
