    Notes: The performance of spherical catalyst pellets with radially nonuniform distributions of activity is simulated under parallel reaction networks closely resembling hydrocarbon oxidation reactions. Both reaction paths are assumed to be exothermic with the desired path exhibiting lower activation energy requirements than the undesired one. It is shown that nonuniform activity distributions enhance effectiveness and selectivity over a large range of values of the Thiele modulus. Multiple steady states in effectiveness and selectivity are observed for certain values of the heat of reaction parameter.

    Notes: Optimal activity distributions within nonisothermal porous hetergeneous catalysts for series and parallel reaction networks are determined employing a numerical search procedure based on orthogonal collocation techniques. At high values of the Thiele modulus, a shell profile is found to be optimal at moderate heat of reaction parameters. In certain cases a pendulum effect, in which activity shifts from shell to core and back to shell profiles, is observed with increasing value of the heat of reaction parameters.
