For aromatic production using natural gas a single step conversion of methane to aromatics under non-oxidative conditions can be an ideal choice for this gas to liquid technology. The active catalyst in this technology is the hcp β-Mo2C supported onHZSM-5 zeolite. The main products from this reaction are aromatic (benzene and naphthalene) and coke. The main function of calcinations is the redistribution of the MoO3 species over the catalyst surface and into the channels of the zeolite or pore. This results in stronger interaction between the MoO3 species and the HZSM-5 zeolite. Based on calcinations temperature studies for 10MoBM at the set parameters, calcinations at 600°C is the preferred temperature for MBA reaction as it has the highest catalytic activity and produces the highest yield and selectivity towards aromatic and lowest coke yield and selectivity. © 2011 Asian Network for Scientific Information.
