EXAMPLE 1 Alkylation of Benzene by a Fraction that is Obtained from the Dehydrogenation of a Kerosene (Under Standard Conditions: Example for Comparison) A reactor that contains 50 cm3 of catalyst that consists of 40% dealuminified Y zeolite, with an Si/Al ratio that is close to 45 in extrudate form, is used. The operating conditions for the alkylation of benzene and a petroleum fraction obtained from the dehydrogenation of a kerosene (fraction that is obtained from the atmospheric distillation of the crude and that has a distillation range of between 150° C. and 240° C.) are standard operating conditions that are known to one skilled in the art: temperature: 135° C. pressure: 4 MPa VVH=1 h-1 benzene/olefin molar ratio: 10/1 A feedstock that contains 32% by weight of benzene and 68% by weight of kerosene fraction that is obtained from the dehydrogenation is prepared. The composition of this fraction is presented in Table 1 below: TABLE 1 Composition of the Fraction that is Obtained from the Dehydrogenation of Kerosene.

It is a mixture of 2-, 3-, 4-, 5-phenylalkanes whose alkyl chain comprises 10 carbon atoms. A C11 LAB is a linear alkylbenzene whose alkyl chain comprises 11 carbon atoms. It is a mixture of 2-, 3-, 4-, 5-, 6-phenylalkanes whose alkyl chain comprises 11 carbon atoms. A C12 LAB is a linear alkylbenzene whose alkyl chain comprises 12 carbon atoms. It is a mixture of 2-, 3-, 4-, 5-, 6-phenylalkanes whose alkyl chain comprises 12 carbon atoms. A C13 LAB is a linear alkylbenzene whose alkyl chain comprises 13 carbon atoms. It is a mixture of 2-, 3-, 4-, 5-, 6-, 7-phenylalkanes whose alkyl chain comprises 13 carbon atoms.
