Abstract
Nonoxidative conversion of methane to aromatic hydrocarbons on granulated Мо/ZSM-5 catalysts was studied. The catalysts prepared using zeolites with the hierarchic pore system surpass in activity the catalysts prepared by the traditional method, mixing of powdered Н-ZSM-5 with pseudoboehmite, followed by granulation and calcination. The textural characteristics of the granulated zeolites and of Mo-containing catalysts based on them were studied. The catalyst samples contain micro-, meso-, and macropores, but the pore formation pattern in the granulated catalysts with the hierarchic pore system and in the catalysts containing 30% binder is different.
