The porous catalyst pellet shown in Figure 1 has an overall radius R and a
thermal conductivity k (which may be assumed constant). Because of the chemical
reaction occurring within the porous pellet, heat is generated at a constant rate
of Se cal/em s. Heat is lost at the outer surface of the pellet to a gas stream at a
constant temperature T, by convective heat transfer coefficient h.
