PRODUCTION OF LIQUID HYDROCARBONS FROM METHANE Russian patent published in 2010 - IPC C07C5/10 C07C5/11 C07C2/76 C10G45/44 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing liquid hydrocarbons from methane. Disclosed is a method of converting methane into liquid hydrocarbons, in which material containing methane is brought into contact with a dehydrocyclisation catalyst under conditions suitable for conversion of said methane to aromatic hydrocarbons, including naphthalene, and obtaining a first effluent containing hydrogen and at least 5 wt % aromatic hydrocarbons more than said starting material. At least a portion of aromatic hydrocarbons from the first effluent then reacts with hydrogen to form a second effluent having lower content of benzene compared to said first effluent, and at least a portion of hydrogen from the first effluent reacts with carbon monoxide, carbon dioxide or mixture thereof to obtain an additional effluent containing water and a hydrocarbon, and at least a portion of the hydrocarbon in said additional effluent is returned to said contact step.

EFFECT: improved method of converting methane to liquid hydrocarbons when methane is contained in a stream of natural gas with large amount of carbon dioxide.
