  • Patent number: 7247276
    Abstract: Described herein is a microreactor for carrying out chemical reactions between a reaction partner in liquid form and a reaction partner in gaseous form, if necessary in the presence of a solid catalyst, whereby the chemical process guidance takes place in spaces that are formed by two or more essentially coplanar plates or layers, with at least one of these plates or layers being a fluid guidance plate (1) that is structured and/or arranged in such a way that the fluid reaction partner flows in at least one essentially uninterrupted capillary thread along the surface of this plate or layer only due to the influence of gravity and/or capillary forces and thereby comes into contact and reacts with the gaseous reaction partner.
    Type: Grant

  • Patent number: 6537506
    Abstract: A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved.
