1. Process for the preparation of a low benzene content, environmentally-acceptable petrol derived from carbonaceous light oil, characterised in that a core fraction boiling at 145-185 degrees C is distilled off from the crude carbonaceous light oil, the phenol in the core fraction is separated out, the separation is conducted by extraction using aqueous soda lye or sodium phenolate lye, and the phenol-free raffinate of the core fraction is mixed with the portion of the carbonaceous light oil boiling at up to 145 degrees C and worked up by raffination and reforming to give a low benzene content petrol having an increased octane number. |
