Method of production of gasoline and of fuel for jet fuel from the butanes and / or of the c4 cuts originating from the cracking or of a catalytic reforming

摘要

The invention relates to a process for obtaining a gasoline and of a fuel for jet engine fuel from a cut rich in 100) coming from a reforming unit or catalytic cracking. & br / the load is subjected to a pick-up ide dehydrogenation 7, and then to an oligomerization reaction 10, the effluent being sent into a train of fractionating columns 12, 17, 20 and 24 in order to separate, at the end of this train, the gasoline cut of the fuel for jet engine fuel, a gaseous fraction rich in hydrogen (line 14) and a fraction rich in butane, isobutane (pipe 21) is recycled towards the zone of dehydrogenation. & br / (see appended drawing in bopi) & br / & & br /
