The present invention refers to a process for the production of high-octane and low benzene content gasolines according to a cycle where a crude oil is fed into an atmospheric distillation unit from which a fraction is obtained called virgin naphtha seat in turn to a splitting unit that produces a fraction called light tops and a fraction called heavy naphtha wherein said heavy naphtha fraction has a six carbon atoms (C6) hydrocarbons content no greater than 0.5% volume, and said light tops fraction has a seven plus carbon atoms C7+) hydrocarbons content no greater than 4% volume. Said process allows in the refinery to contextually obtain quantitative and qualitative improvements in the gasolines production, with increase of the production yield and of the octane number as well as reduction of the produced benzene quantity.
High yield process for the production of high-octane and low benzene content gasolines according to a cycle where a crude oil is fed into an atmospheric distillation unit from which a fraction is obtained called virgin naphtha sent in turn to a splitting unit that produces a fraction called light tops and a fraction called heavy naphtha, respectively sent to a processing unit called isomerization and to a processing unit called catalytic reformer, characterized in that the heavy naphtha fraction has a six carbon atoms (C6) hydrocarbons content no greater than 0.5% volume, and the light tops fraction has a seven plus carbon atoms (C7+) hydrocarbons content no greater than 4% volume.
Process according to any one of the preceding claims, characterized in that the light tops C7+ content must be no greater than 2% volume.
