Multiplicity of steady state in an isothermal catalyst Pellet

Mostrar todas las versiones(2)

CO preferential oxidation (COPROX) reaction was studied using Cu/CeO2 catalyst with sizes in the order of microns. Conversion increased when increasing catalyst size, thus suggesting that the effectiveness factor also increased. The rise of the effectiveness factor suggests the possible existence of...

CO preferential oxidation (COPROX) reaction was studied using Cu/CeO2 catalyst with sizes in the order of microns. Conversion increased when increasing catalyst size, thus suggesting that the effectiveness factor also increased. The rise of the effectiveness factor suggests the possible existence of multiplicity of steady states inside the catalyst pellet. Simulations showed that, although pellets behaved isothermally, multiplicity is possible if the kinetics is non monotonous with respect to the reactants composition.
