1. Introduction
Currently, catalytic steam and autothermal reforming and gasification are common technologies to convert natural gas into synthesis gas; synthesis gas serves as the platform for the manufacture of a wide range of chemicals. The CAPEX and OPEX for the syngas production step are very high, so that it is only profitable to construct large plants. Accordingly, it remains a strong desire of the chemical industry to develop a simple process to upgrade natural gas to liquids. One such process may be the direct aromatization of methane to benzene under non-oxidative conditions (methane dehydroaromatization, MDA). Benzene is an attractive intermediate, because it can be more easily transported than natural gas. In addition, the increasing use of ethane from wet shale gas instead of naphtha to produce ethylene is putting pressure on the aromatics supply. Direct methane to aromatics conversion would be very desirable in this context [1].
