Abstract

A monolithic catalytic converter of automobile exhaust gas was modeled in order to assess the effects of oscillatory feeding on the performance of the reactor with respect to CO oxidn. by O2. Simulations were performed with an oscillating feed compn. of CO and O2. The influence of frequency, amplitude, phase angle and ratios of reactants in the feed on the time av. CO conversion was investigated. An improvement relative to the steady state conversion of 10% max. is obtained at temps. below the light-off temp., at frequencies below 0.1 Hz and an amplitude of 15%. The reverse effect is obtained from temps. slightly above the light-off temp. upwards. These effects are strongest when CO and O2 oscillate in counterphase. The explanation for this effect is given in terms of strongly changing surface coverage during cycling of the feed concns
