FREMGANGSMÅDE OG SYSTEM TIL FREMSTILLING AF EN SYNTETISK KEROSIN UD FRA OXYGENATER

The invention relates to a method for producing a synthetic kerosene, comprising the steps of: I) catalytic production of olefin by reacting oxygenates to form an olefin-containing mixture, II) separation of an olefin-containing fraction from the olefin-containing mixture by absorption using an absorption medium, wherein a remaining circulation gas is returned to step I) and during the absorption in step II) ethylene is returned with the circulation gas, the absorption medium from step II) subsequently being fed directly to an oligomerization in step III) and/or to a separating unit (Va), III) catalytic oligomerization of the olefin-containing fraction obtained in step II) to form an oligomerization product, IV) catalytic hydrogenation of the oligomerization product, V) separation of the absorption medium after step III) in separating unit (Va) and/or after step IV) in a separating unit (Vb). The invention also relates to a corresponding plant and to the use of the plant in the process.
