Abstract:
1. A process for converting methane to higher hydrocarbons including aromatic hydrocarbons, the process comprising: (a) contacting a feed containing methane with a dehydrocyclization catalyst in a reaction zone under conditions comprising a first maximum temperature and effective to convert said methane to aromatic hydrocarbons and generate coke on the catalyst; (b) transferring a portion of said catalyst from the reaction zone to a regeneration zone separate from said reaction zone; (c) contacting said catalyst portion with a regeneration gas in said regeneration zone under conditions effective to at least partially remove coke from said catalyst portion and comprising a second maximum temperature less than or equal to said first maximum temperature; (d) contacting the regenerated catalyst portion with a carburizing gas in a catalyst treatment zone separate from said reaction zone under conditions comprising a third maximum temperature less than or equal to said first maximum temperature, wherein said carburizing gas comprises at least one hydrocarbon; and (e) returning the catalyst portion to the reaction zone.
