Case Study III Heterogeneously Catalyzed Multiphase Reaction

3 Case Study III Heterogeneously Catalyzed Multiphase Reaction 

Multiphase fixed bed reactors have complex hydrodynamic and mass transfer characteristics (see also Section 4.9). Thus, the modeling and scale-up are difficult. As an instructive example, we inspect the catalytic 1-octene hydrogenation as a model reaction (Battsengel, Datsevitch, and Jess, 2002 Battsengel, 2002). Table 4.11.4 lists the characteristics of the commercial Ni-catalyst (NISAT, Siidchemie) used for the experiments, data on chemical media, and the parameters that determine the mass transfer. 

Kinetic studies on the catalytic hydrogenation of 1-octene to n-octane were performed in an agitated batch reactor with suspended catalyst. The primary result of the experiments is the curve of the octane concentration Cq,. versus reaction time. By
