PROCESS FOR THE PRODUCTION OF ALKYLAROMATIC HYDROCARBONS FROM NATURAL GAS INVENTION OF MM. BERNARD JUGUIN, JEAN-CLAUDE COLLIN, JOSEPH LARUE AND CHRISTIAN BUSSON.

摘要

The invention relates to a process for the production of alkylaromatic hydrocarbons from natural gas containing methane, characterized in that it comprises the following three successive phases: BR/ 1) thermal cracking of natural gas with formation of hydrogen and C2 + hydrocarbons, in particular ethylene and acetylene, BR/ 2) separation of C2 + hydrocarbons, in particular ethylene and acetylene, obtained at the end of phase 1) , by refrigerated absorption in a solvent, BR/ 3) conversion of the C2 + hydrocarbons from phase 2) to alkylaromatics. BR/ The alkylaromatics obtained can be used as a base for premium fuel.
