Process for the production of liquid hydrocarbons from natural gas, characterised in that: a) natural gas is separated in (2) into at least two fractions, a first fraction of methane-enriched gas and a second fraction <IMAGE> molecular in the presence of a methane-oxidising coupling catalyst, c) there is mixed, <IMAGE> selective when at least 80 % of the molecular oxygen introduced in stage (b) have already been consumed in stage (b), d) the mixture resulting from stage (c) is pyrolysed in (7b), e) after the temperature of the mixture from stage (d) has been brought to a temperature of between 300 DEG C and 750 DEG C, and more particularly between 450 DEG C and 600 DEG C, the olefins are at least partly converted into aromatics in (11d) and/or (11c) in the presence of an aromatisation catalyst. <IMAGE> |
