The thermal features of different catalytic supports for fixed-bed reactors, namely a SiC open-cell solid foam and three types of alumina beads, were investigated experimentally. The results were analysed by means of a stationary one-equation bidimensional model and show that SiC foam packings are characterized by better radial heat transport because of their higher intrinsic thermal conductivity. However, from a structural point of view, the granular beds appear preferable in order to favor radial heat transport, mainly because of the lower void fraction and higher radial mixing of the gas phase. © 2011, AIDIC Servizi S.r.l.
