A B S T R A C T PROCESS FOR UPGRADING A GASOLINE A complete gasoline fraction obtained by catalytic cracking, which complete gasoline has an aromatics content of a %w and consists of a light and a heavy fraction, said heavy fraction having an aromatics content of b %w such that 0.55 < ? < 0.80, is upgraded by separating the heavy fraction by distillation from the product obtained by catalytic cracking and contacting this fraction with a crystalline metal silicate which after one hour's calcination in air at 500 °C has the following properties: a) an X-ray powder diffraction pattern in which the strongest lines are the four lines mentioned in Table A, Image b) in the formula which expresses the composition of the silicate in moles of the oxides and which, in addition to SiO2, includes Fe2O3 or both Fe2O3 and A12O3, the SiO2/(Fe2O3 + Al2O3 molar ratio is higher than 10, the SiO2/Fe2O3 molar ratio is lower than 250 and the SiO2/Al2O3 molar ratio is at least 500.
