Rotating fixed bed reactor

The inclined rotating fixed bed is a novel reactor concept for process intensification, inducing beneficial flow patterns, which ensures catalyst wetting intermittency by superimposed reactor inclination and rotation.

Monolithic reactors

Two-phase flow in narrow channels with hydraulic dia­meters of a few milli­meters are relevant for micro reactors and structured reactors, compact heat exchangers, micro condensation units or fuel cells due to the low heat and mass transfer resistance between the fluidic layers.

Open-cell solid foams as catalyst carrier for structured reactors

In the course of the Helmholtz Energy Alliance ‘Energy Efficient Chemical Multiphase Processes’, different approaches with the application of open-cell solid foams as catalyst carrier were adopted for the optimization of the example process of the hydrogenation of nitrobenzene to aniline.

Two-phase flow in static mixers

Static mixers are an attractive contactor alternative to the bubble column and mechanically stirred vessels in chemical industries. Small space requirement, low equipment and maintenance costs, sharp residence time distributions and high interfacial area production are the main features of static mixers.

Oxidation of isobutane to TBHP in a micro-reactor

Partial oxidation of hydrocarbons are frequently characterized by low con­versions and yields, which are mostly related to mass and heat transfer problems. Due to their hazard potentials, such processes are still not sufficiently investigated.
