Abstract
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.
