O. 8 and 1.0) were prepared by Co-precipitation method. Characterisation was done by X-ray phase analysis and DRS studies and by measurements of surface area and electrical conductivity. The amount of metallic copper and monovalent copper were estimated by reversible adsorption of CO respectively. Hydrogenation of nitrobenzene to aniline was carried out at 250°C in a fixed bed flow type reactor. Comparison of hydrogenation activity with CO adsorption data show that monovalent copper is more active than metallic copper for the hydrogenation of nitrobenzene.

More tests are needed comparing measured conversions and temperature profiles with model predictions for tubular reactors. Comparisons will be easier for reactions with simple kinetics than for complex reactions such as partial oxidations. Tests should be made over a wide range of Reynolds numbers, which may require high velocities and long reactors. If kinetic data are uncertain or unavailable, the overall heat transfer coefficient for the 1-D model can be obtained from the axial temperature profile and the total heat removal [41] ...

Moholkar and Pandit (2001b) have also extended the nonlinear continuum mixture model to orifice-type reactors. Comparison of the bubble-dynamics profiles indicated that in the case of a venturi tube, a stable oscillatory radial bubble motion is obtained due to a linear pressure recovery (with low turbulence) gradient, whereas due to an additional oscillating pressure gradient due to turbulent velocity fluctuation, the radial bubble motion in the case of an orifice flow results in a combination of both stable and oscillatory type. Thus, the intensity of cavitation...

Different issues also arise for the comparison of different reactors. Furthermore, data in the literature are often not comparable. This is why only reactor comparisons from the literature will be indicated exemplarily in the following text.
