Abstract
CO chemical reaction is gas-solid catalytic reaction in catalytic converter. The mass transfer course of CO in honeycomb holes has very important effects on CO conversion ration. This paper shows: honeycomb holes surface area,
CO density and airspeed makes notable impact on CO mass transfer course. Larger surface area and higher CO density can increase CO mass transfer ration. Airspeed also shows affluence to CO mass transfer course by flow velocity boundary layer or CO density boundary layer. The CO mass transfer coefficient is impacted by flow boundary layer and it linearly increases with airspeed increasing when airspeed value is in a limit scope. Out of this scope the CO mass transfer coefficient increases slowly and tends to steady finally.
