PRODUCING AROMATIC HYDROCARBONS AND SYNTHETIC GAS FROM METHANE Russian patent published in 2012 - IPC C07C2/76 C01B3/36 C07C15/02 C07C15/04 C07C15/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of converting methane-containing starting material into synthetic gas and an aromatic hydrocarbon (hydrocarbons). The method involves: (a) contacting the methane-containing starting material with a dehydrocyclisation catalyst in conditions sufficient for obtaining a first effluent containing said aromatic hydrocarbons, residual methane and H₂, where said first effluent has concentration of aromatic rings which is at least 5 wt % higher than concentration of aromatic rings in said starting material. Further, (b) extracting at least a portion of said aromatic hydrocarbons from said first effluent and then (c) reaction of at least a portion of said H₂ and said residual methane from said first effluent with oxygen-containing materials to obtain a second effluent containing H₂ and CO, where the total number of moles of H₂ and CO in said effluent is greater than the number of moles of H₂ and CO in said first effluent.

EFFECT: method provides improved conversion of methane into aromatic hydrocarbons.
