Özet

The effect of CaC ₂ on the activity of MFI-supported molybdenum catalysts was investigated in the dehydrocyclization of methane. Treatment with CaC ₂ enhanced the activities of the catalysts in comparison to the activities of those which were not precarburized or prepared by precarburization with a CH ₄ /H ₂ mixture. The induction period seen in the case of the sample prepared without precarburization decreased with CaC ₂ treatment. CaC ₂ loading above a certain value, however, gave poor results, possibly due to pore blockage in the support. All samples, precarburized with CaC ₂ or CH ₄ /H ₂ mixture or carburized in the course of the reaction, deactivated in a similar manner after the variable induction period.
