4 u2212 fraction is introduced via conduit 44 into the conduit 12 from where it is fed into the column 14 together with the gaseous part from the compressor 11 via conduit 13 via conduit 45 the bottom product of the column 43 which contains the c 5 fraction is guided into the column 46 from the bottom of the column 46 the c 7 fraction is withdrawn into the conduits 47 and 48 over the head of the column 46 the c 5 c 6 fraction obtained is recycled via the conduits 49 50 51 and 52 in that it is recirculated into the conduit 5 parts of the c 5 and c 6 fraction are supplied to the conduit 47 via conduit 53 and discharged from the process via conduit 48 purge the stream leaving the process via conduit 48 represents the mtp gasoline fig2 schematically shows the procedure of the process according to the invention up to the plant component 47 the plant is identical with the mtp process known from the prior art the c 5 c 6 fraction which has been obtained at the top of column 46 furthermore is recirculated into the oxygenate conversion step i by means of conduit 49 but.
