Reactors - Heterogeneous Catalysis
Two home-built microreactors interfaced with commercial high pressure mass spectrometer systems are available for the rapid screening of catalytic activity. These systems allows real-time continuous analysis of multiple gas components.
Microreactor and integrated mass spectrometer system (HIDEN)
- Ambient Pressure Microreactor: gas manifold with independent inlets for four gases and a vaporized liquid (mass flow controlled) and a high temperature quartz reactor column for easy-access catalyst placement with minimal changeover time. The sample temperature can be tuned within the range of ambient to 600ºC and an "in-bed" thermocouple is available.

- High Pressure Microreactor: gas manifold with independent inlets for four gases and a high temperature stainless steel reactor column for easy-access catalyst placement with minimal changeover time. This reactor can be pressurized up to 20 bar for high pressure reactions.

- Mass Spectrometers (HPR20, HIDEN): Detection of the gases/vapors used or generated in each microreactor can be performed with high sensitivity and fast response using two compact bench top mass spectrometer systems (200 amu mass range dual Faraday/Electron multiplier detector) configured for continuous gas analysis in the pressure range 10 mTorr to 2 bar.
- Gas Chromatograph (Agilent 7890A gas) interfaced to one of the systems to improve the separation of reaction productions. Reaction products from the microreactor enter the gas chromatograph through an inlet and are separated based on their retention time.
