    Abstract: Die vorliegende Erfindung betrifft einen Rohrreaktor (14) zur mehrphasigen Polymerisation, insbesondere zur Herstellung von Butylkautschuk, mit einem Rohrstück (16) zur radialen Begrenzung eines Reaktorvolumens zwischen einem Einlass (18) und einem Auslass (20), einem Rührer (22) zur Erzeugung einer Strömung (27) in radialer Richtung des Rohrstücks (16), wobei der Rührer (22) derart dimensioniert und betreibbar ist, dass der Strömung (27) eine Zentrifugalkraft aufprägbar ist, die eine Konzentrationsverteilung in radialer Richtung innerhalb des Rohrstücks (16) erzeugt, und eine Auslassleitung (32) zur Ableitung eines aufkonzentrierten radialinneren Teils (30) der Strömung (27, 28). Durch die Aufkonzentrierung von Polymer-Partikeln im radial inneren Teil (30) der Strömung (27, 28) wird ein Verkleben des Rohrstücks (16) durch die Polymer-Partikel vermieden, so dass das Risiko einer Verstopfung reduziert ist.

    Abstract: A reaction apparatus includes a first reaction cell fluidly connected to a second reaction cell so that a liquid can be actively transported from the first cell into the second cell. Each reaction cell includes a gas inlet for introducing a gas into the cells to be mixed and reacted with the liquid. The gas inlet of one reaction cell can be connected to a gas outlet of the other reaction cell enabling the gas to flow between cells. A gas processor can be connected in fluid communication between cells to process the gas flowing between the cells. The liquid exiting the second cell can be recycled into the first cell. A liquid processor can be connected in fluid communication with the liquid recycle stream to process the recycled liquid.
