OBTAINING AROMATIC HYDROCARBON FROM METHANE Russian patent published in 2012 - IPC B01J38/10 C07C2/78 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to method for obtaining aromatic hydrocarbons from methane, namely natural gas. Invention relates to method of methane transformation into aromatic hydrocarbons according to which methane-containing initial material and granular catalytic material is supplied to reaction zone, the operation of reaction zone is provided in reaction conditions effective for transformation of at least part of methane into aromatic hydrocarbons with associated deposition of carbonaceous material on granular catalytic material that causes its (catalytic material) de-activation. At least part of de-activated granular catalytic material is removed from reaction zone and heated till the temperature approximately from 700°C to 1200°C by direct or indirect contact with gaseous combustion products obtained by combustion of auxiliary fuel. Then heated granular catalytic material is regenerated by hydrogen-containing gas in conditions effective for transformation of at least part of deposited carbonaceous material into methane and regenerated granular catalytic material is returned back into reaction zone.

EFFECT: improvement of methane aromatisation method.
