METHOD OF CONVERTING METHANE Russian patent published in 2012 - IPC C07C2/76 C07C15/04 C10G50/00 

FIELD: chemistry.

SUBSTANCE: invention relates to versions of the method of converting methane into higher-molecular weight hydrocarbon(s). One version comprises aromatic hydrocarbon(s) in a reaction zone, involving: (a) feeding into said reaction zone hydrocarbon starting material containing methane; (b) feeding into said reaction zone catalytic powdered material; (c) bringing said catalytic powdered material into contact with said hydrocarbon starting material essentially on the counterflow principle; (d) maintaining flow dynamics of said reaction zone with gaseous streams such that the reduced velocity of gas (U) is less than the minimum velocity (U_MP) required for fluidisation of solid particles and (e) operation of said reaction zone in reaction conditions sufficient for conversion of at least a portion of said methane into a first effluent containing said higher-molecular weight hydrocarbon(s).

EFFECT: use of the present invention enables to achieve maximum selectivity with respect to the end hydrocarbons while simultaneously minimising the required catalyst circulation rate.
