Abstract In the approach to a cycle‐invariant state in the forced feed concentration cycling of the CO oxidation over a NiO catalyst, a very long transient has been observed lasting 80 ks or more. This transient appears to be associated only with CO pretreatment of the catalyst and is not a general phenomenon. The slow convergence to the cycle‐invariant state reported in certain modelling calculations in the literature appears to have a different cause.
