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.
