Numerical analysis of the optimal catalyst distribution in created unsteady state conditions

The determination of the optimal distribution of the catalytic activity profile, which maximizes the catalytic effectiveness, in created unsteady state conditions, is analyzed and treated numerically for the case of a simple reaction. It was proven that the modulation, of the temperature and the reactant concentration of the external bulk fluid, leads to a considerable increase of the catalytic effectiveness. The optimal active element distribution is a Dirac- δ function i.e. all the catalyst must be deposited at a specific distance from the center of the catalytic pellet. It was shown that this optimal position changes with time in a sinusoidal manner. This purpose can be achieved by the use of ultrasounds to artificially control the activity profile.
