Liquid hydrocarbons are produced from methane by a process comprising the following steps:- (I) feeding methane to a pyrolysis zone maintained under such conditions that methane is pyrolysed to form a product comprising hydrogen, unsaturated hydrocarbons and aromatic hydrocarbons in a yield exceeding 30% wt, (II) partially quenching the pyrolysis product from step (I) with water to a lower temperature such that carbon formation is essentially prevented, (III) further quenching the product from step (II) or the product from (II) which has been subjected to oligomerisation and/or alkylation, with a liquid hydrocarbon to a temperature low enough to condense condensible components of the pyrolysis product, thereby achieving gas/liquid product separation. The liquid product from III may be hydrogenated. |
