Coke goes to prison: Heterogeneous catalysis of methanol conversion is investigated through simultaneous measurements of volatile products and confined coke deposition. Complete and real-time reaction profiles are plotted for evaluation of carbon atom economy of the conversion. The deposited coke products have been determined, and a new species has been detected, which is responsible for fast deactivation of the catalyst and low carbon atom economy at low temperatures.
