In order to gain a better understanding of the chemistry of methanl-to-hydro-carbon conversion, it is necessary to determine the nature of the primary reaction products. Experiments carried out in this work on H-ZSM-11, using a continuous flow reactor linked to an on-line gas chromatograph demonstrated that ethylene and methane are the primary reaction products. The results obtained using solid state MAS NMR for the same reaction further support the findings of this work. The results from H-ZSM-5 catalyst do not confirm that the CO of the reaction acts as a catalyst.
