It takes two : A high level of conversion of 13 C atoms of methane into the products of methane/propane coaromatization on zeolite Zn/H‐BEA has been demonstrated by 13 C solid‐state NMR spectroscopic analysis and GC‐MS. The isotope‐labeling experiments show the mechanism consists of the methylation of aromatic compounds formed from the propane followed by ring‐expansion/contraction (see scheme).
