Abstract (EN): Heat transfer parameters were measured in fixed bed exchangers containing alumina catalyst particles with particle diameter dp = 3.1 × 10-3 m. Different tube diameter (dt) to particle diameter ratios were used, ranging from 3 to 18. Radial temperature profiles were measured at various axial positions. Results were analysed on the basis of a pseudohomogeneous unidimensional model leading to an overall wall heat transfer coefficient hw, which showed a maximum value at dt/dp ¿ 6. Experimental results were also analysed by means of a pseudohomogeneous bidimensional model from which the wall heat transfer coefficient ¿w and the effective radial thermal conductivity ¿er were calculated as a function of the particle Reynolds' number. © 1987.
