Catalyst preparation and methods of using such catalysts

摘要

A process for the pre-treatment of Mo/ZSM-5 and Mo/MCM-22 catalysts is provided, which process comprises heating the catalyst at 500° C. in the presence of propane. The treated catalyst, when used in the non-oxidative dehydrogenation of methane demonstrates improved benzene yield and catalyst stability as compared to catalysts pre-treated with He, methane or H2.

1. A process for preparing a methane dehydroaromatization catalyst comprising the step of heating a catalyst precursor comprising molybdenum supported on a zeolite, wherein the zeolite is selected from zeolites having a framework type MFI and zeolites having a framework type MWW, at a temperature of at least 300° C. to less than 700° C. in the presence of a treatment gas, wherein the treatment gas consists of propane.
