REACNOSTICS is modeling, constructing and building chemical research reactors
for the spatially resolved investigation of catalytic processes.
Our methodologies comprise simulations and operando measurements of concentration & temperature profiles
in combination with spectroscopic catalyst characterization.
By applying patented methods we provide insight in catalytic reactors during time on stream
required for knowledge based optimization.
NEWS - Combined Operando Reactor and X-Ray Absorption Spectroscopy Profiling
Transition metal oxide catalysts are often applied in selective oxidation catalysis. They can change their oxidation state easily and lattice oxygen takes part in the catalytic cycle.
In a recent joint cooperation between TUHH, KIT, BasCat, DESY and Reacnostics we demonstrate the simultaneous spatially resolved measurement of concentration-, temperature- and X-ray absorption spectroscopy profiles through a fixed-bed reactor during oxidative dehydrogenation of ethane to ethylene on a molybdenum oxide catalyst. By applying our compact profile reactor modified for synchrotron studies, a kinetic reaction model could be developed in a very short time including the oxidation state of the catalyst and providing a link between catalyst structure and reactivity.
