Multiplicity of steady state in an isothermal catalyst Pellet

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...
