Channel widths can be as small as 12 m and have aspect ratios greater than 800. The diffusion bonding process forms a sealed monolithic unit. This concept is not limited to simple microchannel components. Components capable of mixing multiple materials with multiple fluid and gas flow paths can be fabricated just as easily as the simple single channel device. It is also possible to integrate membranes, catalysts, and coatings into the laminated components.
Complex geometries are straightforward.
Curved sections with curved channels to fit pipes or cylindrical reactor elements for localized heating and cooling can readily be fabricated. The fabrication process is mass production amenable, easily automated, and uses low cost materials.
