Embodiment Construction

[0025] Detailed description of the preferred embodiment

[0026] The disclosed porous membrane microstructure devices can be used in separator, extractor, diffuser and contactor applications. Conventional micro-lamination processing steps are not required when manufacturing the porous membrane microstructure device, which obviously saves cost. The overall configuration of the disclosed porous membrane microstructure provides, among other functions, sufficient mechanical support for the porous membrane and substantially eliminates leakage during chemical processing. The disclosed method for fabricating porous membrane microstructures combines low fabrication costs, facilitates parallelization, and yields devices that provide excellent yields.

[0027] The present invention broadly relates to membrane microstructures and methods of making them. Such membrane microstructures are particularly suitable for chemical processing applications and may be configured to facilitate catal...

Abstract

A membrane microstructure device (10) is disclosed. The membrane microstructure device (10) includes a first glass, ceramic or glass-ceramic plate (12) defining a first recess (16), a second glass, ceramic or glass-ceramic plate (20) defining a second recess (24), and a non-metallic porous membrane (30) sandwiched between the first and second plates (12,20). The first plate (12), second plate (20) and porous membrane (30) are joined together and the porous membrane (30) is arranged to cover the first and second recesses (16,24) to define a first microchannel between the first plate and the porous membrane and a second microchannel in fluid communication with the first microchannel between the second plate and the porous membrane. A method of manufacturing a membrane microstructure device is also disclosed.

Description

field of invention [0001] The present invention relates generally to the field of microstructured devices, and more particularly to microstructured devices incorporating porous membranes. [0002] Although the invention has wide applicability, it is particularly applicable to extractors, separators, diffusers and contactors in the field of microfluidic reactor systems. Background technique [0003] Reactor systems incorporating porous membranes are commonly referred to as membrane reactors, which are typically used to separate multi-phase complex feedstocks, or to filter single-phase materials. In general, porous membranes in conventional membrane reactors can range from microporosity to macroporosity and can be fabricated from various materials. Porous materials are usually classified according to their (average) pore size. Microporous materials typically have pore sizes less than or equal to 10 nanometers (nm), mesoporous materials typically have pore sizes in the range ...
