Reaction Engineering

The concept of process intensification has increasingly found its way into industry and science in recent years. In our research, we therefore try to link different key points of process intensification with the complex challenges of homogeneous catalysis with focus on phase contact and recycling strategies. Besides the usage of standard reactor setups like continuous stirred tank- or plug-flow-reactors we aim to investigate innovative reactor concepts like for example the Jetloop-reactor or different types of Membrane-reactors. In addition, all the investigations of reactor concepts go hand in hand with the determination of the reactions-kinetics to predict yields and selectivity and develop a powerful tool for transferring batchwise operated lab scale reactions to continuously operated miniplants using innovative reactor concepts.

Jetloop Reactor

The mentioned Jetloop-Reactor allows us a high energy input to generate huge phase-contact surfaces to overcome limitations of mass transport between non-mixing phases and a downstream phase separation for a simple recycle of homogeneous catalyst. This can result in high activity of the catalyst and therefore fast reaction rates without the additional need of phase contact agents.

Taylor-Couette

This reactor concept consist of two concentric cylinders rotating in relation to each other, which results in the formation of vortices in the annular gap. They rotate in opposite directions, are very well mixed but offer only minor mass transfer between each other. All this leads to a highly controllable system, which has a residence time distribution similar to a plug flow reactor but e.g. decouples the hydrodynamic properties from the feed flow.

Membrane Reactors

With the concept of membrane reactors we are able to separate the catalyst without thermal stress and its inherent loss of activity. With various available membrane-modules it is possible to connect different types of reactors to a membrane and examine novel process designs.

Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dort­mund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dort­mund-Dorstfeld” (closer to North Campus). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

TU Dort­mund University has its own train station (“Dort­mund Uni­ver­si­tät”). From there, suburban trains (S-Bahn) leave for Dort­mund main station (“Dort­mund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dort­mund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop “Dort­mund Kampstraße”. From there, take U43 or U44 to the stop “Dort­mund Wittener Straße”. Switch to bus line 447 and get off at “Dort­mund Uni­ver­si­tät S”.

The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on North Campus. One (“Dort­mund Uni­ver­si­tät S”) is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
