Le Tour de MTO: A complete working catalytic cycle for the conversion of methanol to olefins in HZSM-5 is reported in full consistency with both experimental and theoretical observations. This particular route includes carbon-atom scrambling into a methylbenzene ring, NMR-observed cationic intermediates, and the production of isobutene.
