1. Single stoichiometry catalytic transformation under isothermal conditions
We assume a reaction with the following stoichiometry:A → P
whose velocity law per unit mass of catalyst is of order n with respect to reagent A, i.e. :
rM = k (T ) C n
Since the catalyst particle is represented by a pseudo-homogeneous model (see [J 1 091] § 2.2) (here the half-thickness sheet model = V /S ), in steady state and in the absence of internal convective flow, the differential material balance between thicknesses x and x + dx, is written :
