    CRC 1615 - Project C03: SMART multiphase reactor for the catalytic hydrogenolysis of glycerol
    The kinetics and process parameters of the hydrogenolysis of glycerol to 1,2-propanediol are investigated in a slurry reactor at the beginning of the funding period. The SMART reactor is simultaneously calculated, designed and subjected to a HAZOP, considering the data obtained in the slurry. The final design is worked out in detail and manufactured subsequently. After assembly, the EIT, electrowetting and further measuring and control devices are installed in the reactor. The hydrogenolysis is finally realized in the SMART reactor and the various new components are tested.

    CRC 1615 - Project A02: Quantitative real-time 3D electrical impedance tomography of multiphase reactors
    Project A02 develops the methodology of quantitative, real-time, 3D Electrical Impedance Tomography (EIT) for process monitoring in the SMART multiphase reactor for catalytic hydrogenolysis of glycerol. In A02, EIT will be combined with synchronized capillary sampling of multiphase flows, converting impedance data into process variables like gas-holdup, bubble size distribution and phase flow rates. An EIT measurement cell will be built featuring a higher number of electrodes (100-400) than existing systems (32) for performing EIT over a frequency range (100 kHz-1 MHz) on water/glycerol/propanediol/hydrogen flows at temperatures up to 250°C and 50 bar H2 pressure. Tailored measurement electronics and reconstruction algorithms will be developed.
