The most prestigious catalyst applied in natural gas (methane) non-oxidative conversion to petrochemicals is 6%Mo/H-ZSM-5. Chromium, molybdenum and tungsten are the group VI metals. Hence, in this work, 6%Mo/H-ZSM-5 was correlated with 3%Cr+3%Mo/H-ZSM-5 and 3%W+3%Mo/H-ZSM-5 as catalysts to examine their promoting or inhibiting effects on the various reactions taking place during methane conversion. The catalytic activities of these catalysts were tested in a continuous flow fixed bed reactor at 700°C and a GHSV of 1500 ml g-1 h-1. Characterization of the catalysts using XRD, TGA and TPD were investigated. XRD and NH3-TPD showed greater interaction between the W-phase and the Bronsted acid sites in the channels of the zeolite than between Cr-phase and the acid sites in the zeolite. The most prestigious catalyst applied in natural gas (methane) non-oxidative conversion to petrochemicals is 6% Mo / H-ZSM- 5. Chromium, molybdenum and tungsten are the group VI metals. Therefore, in this work, 6% Mo / H ZSM-5 was correlated with 3% Cr + 3% Mo / H-ZSM-5 and 3% W + 3% Mo / H-ZSM-5 as catalysts to examine their promoting or inhibiting effects on the various reactions taking place during methane conversion.
