HEAT-TRANSPORT IN A WALL HEATED TUBULAR PACKED-BED REACTOR AT ELEVATED PRESSURES AND TEMPERATURES

At different flow rates, pressures and temperature levels heat transfer parameters according to both one- and two-dimensional pseudo-homogeneous model without axial dispersion were determined from steady state temperature measurements in a wall heated tube packed with an industrial ring shaped catalyst. For the effective radial conductivity the following correlation was obtained. The influence of effective axial conductivity was found to be negligible for our experimental conditions. Inclusion of effective axial heat conductivity is not required for heat transfer experiments when appropriate boundary conditions are chosen in the heat transfer model. © 1992, Taylor & Francis Group, LLC.
