Title (DE) VERFAHREN UND VORRICHTUNG ZUR DURCHFÜHRUNG CHEMISCHER REAKTIONEN MITTELS EINES MIKROSTRUKTUR-LAMELLENMISCHERS
(EN) METHOD AND DEVICE FOR CARRYING OUT CHEMICAL REACTIONS USING A MICROLAMINAR MIXER
(FR) PROCEDE ET DISPOSITIF POUR EFFECTUER DES REACTIONS CHIMIQUES AU MOYEN D'UN MELANGEUR MICROLAMINAIRE
Abstract:
(DE) Bei dem Reaktionsverfahren werden mindestens zwei Edukte A, B durch eine ihnen jeweils zugeordnete Schar von schlitzförmigen Mikrokanälen (1a, 1b) in räumlich getrennte Fluidlamellen aufgeteilt, die anschliessend in einen gemeinsamen Misch- und Reaktionsraum austreten. Die Fluidlamellen haben dabei eine Dicke < 1000 $g(m)m, vorzugsweise < 100 $g(m)m, bei einem Breiten/Dickenverhältnis von mindestens 10. Wesentlich ist dabei, dass man die Edukte A, B als dünne Fluidlamellen (6a, 6b) in den Misch/Reaktionsraum austreten lässt, wobei jede Fluidlamelle (6a) eines Edukts A in unmittelbarer Nachbarschaft zu einer Fluidlamelle (6b) eines anderen Eduktes B in den Misch/Reaktionsraum geführt wird. Die benachbarten Fluidlamellen (6a, 6b) vermischen sich dann anschliessend durch Diffusion and/oder Turbulenz. Dadurch wird der Vermischungsvorgang im Vergleich zu konventionellen Reaktoren wesentlich beschleunigt. Bei schnellen chemischen Reaktionen wird auf diese Weise die Bildung von unerwünschten Neben- bzw. Folgeprodukten weitgehend verhindert.
(EN) Described is a method of carrying out a reaction between at least two reactants (A, B) each of which is divided by an array of slit-shaped microchannels (1a, 1b) into separate laminae of fluid which subsequently emerge into a common mixing and reaction chamber. The laminae of fluid have a thickness of < 1000 $g(m)m, preferably < 100 $g(m)m, and a width:thickness ratio of at least 10. The invention calls for the reactants (A, B) to be made to emerge into the mixing/reaction chamber as thin laminae of fluid (6a, 6b), each lamina (6a) of reactant A being fed into the mixing/reaction chamber in the immediate vicinity of a lamina (6b) of reactant B. The adjacent laminae (6a, 6b) subsequently mix in the chamber by diffusion and/or turbulence. The mixing process is thus accelerated significantly compared to conventional reactors. With rapid chemical reactions, this enables the formation of undesired side-products or further-reaction products to be avoided to a considerable extent.
(FR) Selon ce procédé de réaction, au moins deux éduits A et B sont divisés par une série de microcanaux en forme de fentes (1a, 1b) en lamelles fluidiques spatialement distinctes, qui aboutissent dans une chambre de mélange et de réaction commune. Les lamelles fluidiques ont une épaisseur inférieure à 1000 $g(m)m, de préférence inférieure à 100 $g(m)m, avec un rapport largeur/épaisseur égal ou supérieur à 10. Selon l'invention, les éduits A et B sortent de la chambre de mélange/réaction sous forme de fines lamelles fluidiques (6a, 6b), chaque lamelle fluidique (6a) d'un éduit A pénétrant dans la chambre de mélange/ réaction à proximité immédiate d'une lamelle fluidique (6b) d'un autre éduit B. Les lamelles fluidiques voisines (6a, 6b) se mélangent ensuite par diffusion et/ou turbulence, ce qui accélère notablement le processus de mélange par rapport aux réacteurs conventionnels. Ces réactions chimiques rapides empêchent dans une large mesure la formation de sous-produits ou de produits secondaires indésirables.
