Patent ID: 7867383

Claim:
A process for producing fractions from a catalytic hydrocarbon, in which catalytic hydrocarbon feed is fractionated in one or more stages to produce a gasoline fraction, a diesel fraction and an intermediate fraction, the gasoline fraction boiling at 35 to 110° C.±30° C., the diesel fuel fraction boiling at 210±30° C.-355±30° C., and the intermediate fraction boiling at 120±30° C.-210±30° C. and the intermediate fraction, optionally after recombination with part or all of the gasoline fraction, is subsequently extracted at a solvent extractor to separate an aromatic fraction and a non-aromatic fraction, said fractionation being carried out by either use of a single fractionator from which three separate products, the gasoline fraction, the intermediate fraction and the diesel fraction are taken or by use of two fractionators, the first fractionator separating the feed into either a gasoline fraction and a higher boiling fraction or into a diesel fraction and a lower boiling fraction and thereafter in a second fractionator fractionating the higher boiling fraction to produce an intermediate fraction and a diesel fraction or fractionating the lower boiling fraction to produce an intermediate fraction and a gasoline fraction.
