In production of a zeolite membrane complex, a starting material solution containing at least a structure-directing agent and FAU-type zeolite particles having an average particle diameter of 50 to 500 nm is prepared. Then, a support is immersed in the starting material solution to form a zeolite membrane on the support by hydrothermal synthesis, the zeolite membrane being composed of AFX-type zeolite. After that, the structure-directing agent in the zeolite membrane is removed.

A zeolite membrane complex includes a porous support, and a zeolite membrane formed on the support. The zeolite membrane includes a zeolite crystal phase constituted by a plurality of zeolite crystals, and a dense grain boundary phase, which is a region between the plurality of zeolite crystals. A density of at least part of the grain boundary phase is smaller than a density of the zeolite crystal phase. A width of the grain boundary phase is 2 nm or more and 10 nm or less. Accordingly, it is possible to realize high permeability and high separating performance, and high durability of the zeolite membrane.

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.

A housing of a separation apparatus includes therein a zeolite membrane complex. A sheath includes therein the housing. A fluid supplied to the inside of the housing has a temperature higher than the temperature around the sheath. A second exhaust port is used to exhaust a permeated substance that has permeated through the zeolite membrane complex in the fluid to the outside of the housing. The permeated substance exhausted from the housing can be led into an exterior space between the sheath and the housing through the second exhaust port and can be exhausted through an exterior exhaust port. At least part of the zeolite membrane complex is included in an inter-port space surrounded by the sheath, the second exhaust port, and the exterior exhaust port. This structure reduces energy required for fluid separation performed under high temperatures.

This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.
