A complete catalytic cycle … for the conversion of methanol into olefins (MTO) in zeolite HZSM‐5 is presented by J. F. Haw et al. in their Communication on page 5179 ff. The cycle is fully consistent with theoretical and experimental observations, and can be compared to a cycling race, with stages leading up to a finish that coincides with the starting point. For each stage, specific reaction barriers need to be overcome, as in the mountain stages of the Tour de France which separate the wheat from the chaff.
