Multiphase reactors are widely used in the chemical industry. Especially trickle bed reactors are often used, due to the high residence times, which compensate low diffusion rates. Examples are hydrogenation processes of olefins, oxidations of glucose, desulfurization of crude oils and phenol oxidations. In order to improve this kind of reactor an innovative reactor concept is investigated at HZDR, which enhances the mass transfer from the gas-phase to the catalyst. The aim is to ensure an intermittency wetting of the catalyst by the superposition of inclination and rotation. To identify beneficial process windows modelling approaches are very important to reduce time consuming experiments.

The first task is to execute simulation studies with a reactor-particle-model to identify beneficial process windows. On demand further model improvements like the integration of a heat balance or different boundary conditions are possible. Eventually, comparisons between the new model and conventional trickle bed reactors are planned. MATLAB will be used as simulation tool.
