Direct conversion of methane, the main constituent of natural gas to versatile liquid fuel looks lucrative. Gas to liquid (GTL) via syngas production to syn-crude a commercialized but expensive licensed technologies route are available. Methane dehydro-aromatisation (MDA) an alternative single step conversion of methane to aromatics has made some encouraging progress. Conversion to methane under non-oxidative conditions to aromatics is much more favorable thermodynamically than olefins. The active catalyst in this technology is the hcp β-Mo2C supported on HZSM-5 zeolite. The reaction was carried out in a quartz tube reactor using this catalyst at ambient pressure and reaction temperature of 700°C. The main products from this reaction were aromatic (benzene & naphthalene) the favored product and coke which rapid deactivate the catalyst. Coke deposition although undesirable is important at the initial stage of MDA because it is one of the active components of the said reaction The main objective of this study is to optimize catalytic activity i.e. increase methane conversion with high selectivity towards aromatic, reduced coke formation and improved catalytic stability. The Mo metal loading of between 3 to 10wt % was the main process variable used for this reaction. From this study on % Mo loading, it can be concluded 10wt % is the preferred catalytic loading for MDA reaction. It has the highest average methane conversion (7.9%) aromatic yield and selectivity (64%). Further the 10 wt % Mo catalyst is more stable than either 3 or 5 wt% Mo counterpart.
