✦ Synopsis


Using variational techniques, a computationally efficient procedure is developed for determining the sensitivity of the observed reaction rate in a porous catalyst with external transport resistances. Derivatives of the observed rate with respect to bulk fluid conditions or any other parameters in the mathematical model of the catalyst may be easily calculated for slab, cylindrical, or spherical catalyst geometry.

A problem of simultaneous heat and mass transfer in a porous catalyst in a nonuniform external field is solved. The behaviour of such systems for a sphere as well as an infinite slab is investigated. A relaxation procedure for solving the nonlinear elliptic equations describing heat and mass transfe
