Abstract (en)
Process for hydroisomerisation of feedstocks originating from the Fischer-Tropsch process, in which a) hydrogen is reacted with the feedstock in contact with a catalyst 1 in a first reaction zone, the said catalyst 1 comprising at least one alumina-based matrix and at least one component for hydrodehydrogenation, b) the effluent originating from the first reaction zone is brought into contact with a catalyst 2 in a second reaction zone, the said catalyst 2 comprising - from 20 to 97 % by weight of at least one matrix - from 3 to 80 % by weight of at least one zeolite Y in hydrogen form, the said zeolite being characterised by an SiO2/Al2O3 molar ratio higher than 4.5, a sodium content lower than 1 % by weight, determined on zeolite calcined at 1100 DEG C, an elementary crystal lattice constant a0 lower than 24.70 x 10<-10> m, and a specific surface, determined by the BET method, greater than 400 m<2>.g<-1>, - at least one component for hydrodehydrogenation.
