Mathematical models of the monolith catalytic converter: Part II. Application to automobile exhaust

Calculations are done for a series of mathematical models for a monolith catalytic converter to oxidize carbon monoxide in automobile exhaust. Phenomena studied include axial conduction in the wall, diffusion and conduction in the gas in a transverse direction perpendicular to the flow direction, multiple steady states, and transients giving wall temperatures exceeding the adiabatic temperature.
