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. (C)
