A homogeneous-heterogeneously catalysed reaction system in a loop reactor

Catalytic three-phase reactions including homogeneous liquid-phase steps we re simulated in a loop reactor. The loop reactor consisted of a reaction ve ssel, an external loop as well as an ejector. The loop reactor was modelled using tanks-in-series or alternatively, axial dispersion models. Kinetics of the reductive alkylation of aromatic amines, which was determined from t he experiments in a laboratory autoclave, was used for verifying the reacto r model and for concentration profile simulations in the loop reactor.
