Abstract

For the first time, an Ag-based catalyst is used in the gas phase non-oxidative dehydrogenation of methanol to dimethoxymethane. Auto-reductive behaviour of Ag species is observed, and the dynamic Ag oxidation state is identified as descriptive for the dynamic reaction course. Stability and regeneration tests reveal robust properties of the Ag/Hβ bifunctional catalyst.
