Tubular flow reactor for monolithic catalysts with in-situ probe technique (SpaciPro)

Tubular flow reactor for monolithic catalysts. Ex-situ measurements of complete gas outlet as well as in-situ measurements of the gas phase and the temperature in a single channel (capillary-based technique). Analysis of gas composition by FTIR, EI-MS and IMR-MS. Facility used for studies on high temperature catalysis and exhaust-gas aftertreatment.

Tubular Flow Reactor for gas/liquid mixtures (CPOX 2)

Tubular flow reactor for monolithic catalysts as well for packed bed configuration. Dosing of a liquid and water plus gases possible. Fuel liquid can be dosed via a 2-Components-Spray Nozzle into the reactor, water is evaporated downstream the reactor. Ex-situ measurements of complete gas outlet only. Analysis of gas composition by FTIR, IMR-MS, and Paramagnetic Oxygen Analyzer. Facility used for both studies on high temperature catalysis and exhaust-gas aftertreatment.

CATHLEN (Catalysis at high temperature laser environment)

Laser setup (Nd:YAG & dye laser) using PLIF (planar laser induced fluorescence) and Raman spectroscopy for spatially resolved in-situ studies of heterogeneously catalysed gas phase reactions. The gas flow is additionally analyzed by ex-situ techniques such as FT-IR, MS, GC-MS.

Tubular flow reactors for Chemical Vapour Impregnation/ Chemical Vapour Deposition

Tubular flow reactors used for the deposition of solids from per¬ma¬nent gases, e. g. Car¬bon from light hydrocarbons. Analysis: ex situ by gas chro¬ma¬to¬gra¬phy. The equip¬ment can easily be adapt¬ed to using eva¬po¬rat¬ed liquids such as Methyltrichlorosilane (de¬po¬sition of SiC), Tita¬ni¬um¬tetrachloride (deposition of TiN), ethanol (deposition of Car¬bon) and others.

Two-Zone-Fluidized-Bed-Reactor

Due to the two reaction zones this reactor is able to realize reactions which are not possible in other reactor types because of catalyst deactivation. In one Zone the catalyst is regenerated and in the other Zone the catalytic reaction takes place. Two separated gas inlets and the particle exchange in a fluidized bed enables this application. A good example is the dehydrogenation of alkanes.
