The problem of the optimal design of a catalyst pellet occupied by different types of active sites was formalized and solved for a non-isothermal system of two consecutive chemical reactions. The maximization of the desired product yield was tackled with model-order reduction techniques. Proper Orthogonal Decomposition (POD) and Discrete Empirical Interpolation Method (DEIM) were employed to reduce the catalyst pellet balance equations that need to be resolved to evaluate the objective function. It was demonstrated that the pellet performance may be significantly improved by choosing proper fractions of two types of catalytic active centers. Moreover, application of the model-order reduction procedure permitted to solve the problem with a minimal numerical effort without affecting significantly the accuracy.
