Shape‐Selective Zeolites Promote Ethylene Formation from Syngas via a Ketene Intermediate

The eight‐membered‐ring side pockets of mordenite can effectively steer the conversion of ketene intermediates, formed over ZnCrOx during syngas conversion, toward ethylene with a selectivity of 73 % at a CO conversion of 26 %. By comparison, methanol intermediates are mainly converted over the 12‐membered‐ring sites of MOR and result in a remarkably different product distribution dominated by longer‐chain hydrocarbons.
