Abstract:
1. A system for preparation of a high quality gasoline through recombination of catalytic hydrocarbon, comprising a fractionator, a light gasoline hydrogenation reactor and an extractor, wherein a feeding material is fed into the fractionator and separated into light gasoline and heavy gasoline in the fractionator, an upper part of the fractionator is connected with the light gasoline hydrogenation reactor through a light gasoline pipeline, and the light gasoline from the fractionator is fed into the light gasoline hydrogenation reactor through the light gasoline pipeline; a lower part of the fractionator is connected with the extractor through a heavy gasoline pipeline, and the heavy gasoline is fed into the extractor through the heavy gasoline pipeline; the heavy gasoline is extracted and separated into aromatic hydrocarbon and raffinate in the extractor; and the aromatic hydrocarbon is discharged from a lower part of the extractor which is operatively connected to the light gasoline hydrogenation reactor, and is blended with hydrogenated light gasoline from the light gasoline hydrogenation reactor to form the high quality gasoline.
