In this article, stable isothermal multiplicities were observed during carbon monoxide oxidation in an integral reactor, filled with alumina supported platinum catalysts, in the conversion-temperature, conversion-inlet carbon dioxide concentration and conversion-mass flow rate domains.Abstract:
Stable isothermal multiplicities were observed during carbon monoxide oxidation in an integral reactor, filled with alumina supported platinum catalysts. The multiplicities were investigated in the conversion-temperature, conversion-inlet carbon monoxide concentration and conversion-mass flow rate domains. The region of multiplicities was found to widen significantly upon catalyst aging which enhanced the pellets' diffusive resistances. Several intermediate stable steady states were found between the highest and lowest steady states, both experimentally and theoretically. All the above phenomena could be well interpreted by the interactions of the kinetics of carbon monoxide oxidation with intrapellet diffusion resistances.read more

Kinetics of the oxidation of co on Ni/Al2O3 in excess oxygen
TL;DR: In this paper, a non-uniform catalyst surface containing NiO was proposed for a reaction mixture on Ni/Al2O3 and the critical effects involving sharp change in catalyst are smoothed out and the activity remains high.

Behavior of three‐way catalyst in a hybrid drive system
TL;DR: In this article, the dynamic behavior of a Pt-Rh/CeO2-Al2O3 three-way catalyst under pulsed flow operation conditions (intermittent mode), such as occur in a newly developed hybrid drive system, has been studied experimentally in a laboratory apparatus with simulated exhaust gas.
