摘要：

A transient model for oxidation of methane over Pt/Al2O3 monolith catalysts has been developed by rigorous consideration of mass- and heat transport and mean-field treatment of the reaction kinetics. By coupling a virtual regulator using the reactant slip, methane or oxygen partial pressures, or oxygen surface coverage as feedback variable(s) as such or in combinations for control of feed composition, the influence of gas composition changes on the methane conversion has been investigated.
