Abstract: Two heat transfer parameters, the radial effective conductivity ker and the wall heat transfer coefficient hw were estimated by means of non-linear least square. The two-dimensional pseudohomogeneous model was solved by using orthogonal collocation. A fixed bed packed with vanadium-phosphorous catalyst for oxidation of n-butane to maleic anhydride was studied. The temperatures at forty collocation points along the radial direction were measured by a multi-channel potential logger. The effects of bed height, particle Reynolds number, tube diameter to particle diameter ratio, and wall temperature on kei, and hw were investigated, and the following correlations were proposed (5.5
