- Abstract
The article numerically analyzes chemically reacting gaseous flows in catalytic monoliths. The analysis investigates the effect of varying operating conditions and catalyst loading upon the optimization of product yields. Two-dimensional boundary layer equations (BLEs) are used to model the fluid dynamics of the single monolith channel. Large elementary-step reaction mechanisms function as descriptors for the surface and gas-phase chemical reactions, and an optimal control problem is developed. The approach is used to optimize the oxidative dehydrogenation of ethane to ethylene over platinum.
