Abstract
The invention relates to a process for producing alkylaromatic hydrocarbons from natural gas containing methane, characterized in that it comprises the following three successive stages: PA0 1) thermal cracking of the natural gas with forming of hydrogen and C.sub.2.sup.30 hydrocarbons, particularly ethylene and acetylene, PA0 2) separation of the C.sub.2.sup.+ hydrocarbons, particularly of the ethylene and the acteylene, obtained at the end of stage 1), by cooled absorption in a solvent, PA0 3) conversion of the C.sub.2.sup.+ hydrocarbons from stage 2) into alkylaromatics. The obtained alkylaromatics can be used as a base for premium gasoline.
