We use Lyapunov Schmidt (L-S) reduction technique of bifurcation theory to develop reduced order models for catalytic monoliths with multiple washcoat layers for multicomponent systems including homogeneous reactions in the flow channel and non-isothermal case. The reduced order is expressed in the multi concentration/temperature modes and interfacial fluxes which are related through various transfer/cross-transfer coefficients. We show that the multi-scale averaged models obtained by this method are accurate and speed up the calculations by several orders of magnitude. We also illustrate the use of reduced order models by examining some special cases and discuss its utility for real time optimization, solving inverse problems, parametric/bifurcation studies.
