✦ Synopsis
Zeolites with gallium cations on extra‐framework positions are interesting catalysts, e.g., in the conversion of methylcyclohexane to a synthetic steamcracker feed consisting mainly of light n‐alkanes. Due to the bulky hydration shell of Ga^3+^ cations, solid‐state ion exchange instead of ion exchange in aqueous suspension has to be used to introduce gallium cations into the pore system of medium‐pore zeolites. In this work, the solid‐state reaction of acidic zeolites with elemental gallium is presented as an alternative route towards Ga‐containing catalysts.
