Mass transfer resistances in zeolite NaCaA after different hydrothermal pretreatment are probed by NMR tracer desorption studies with the short‐chain‐length hydrocarbons from methane to n ‐butane and with xenon. In all cases, the measurements lead to the coinciding result of forming surface barriers, which differ only slightly depending on the pretreatment modes, but lead to a retardation of molecular mass transfer more dramatically than the starting material. The dramatic retardation of mass transfer after hydrothermal pretreatment is confirmed by supplementary uptake measurements with n ‐decane.
