METHANE CONVERSION OVER Mo/Al2O3 – CATALYSTS MODIFIED WITH ADDITIVES OF ZEOLITE AND PHOSPHOROUS
Ключевые слова:Dry and Combined Dry-Steam Conversion of Methane, Syngas, Molybdenum, Zeolite, Phosphorus.
Mo-containing catalysts supported on a matrix consisting of alumina modified with additives of both
zeolite – HZSM and phosphorus were synthesized. The molybdenum content was varied within a range of 1-5
mas.%. The physicochemical properties of the catalysts were studied by BET, XRD, electron microscopy, and
microdiffraction analysis. The catalytic properties of the synthesized catalysts were tested in the processes of dry and
combined steam-dry conversion of methane. It was shown that the synthesized catalysts are the nanosystems with
particle sizes are 3-50 nm depending on the amount of molybdenum and the processing methods of the catalysts. The
activity of the catalysts grows with increasing of both molybdenum content and temperature. The main product of
methane conversion is synthesis gas. The Н2/СО ratio increases at adding steam to an initial feed. In dry reforming of
methane the reaction products also contain C2, C6 hydrocarbons and alcohols.
