Hydrocracking process paraffins obtained by the method of Fischer-Tropsch with the help of catalysts based on zeolite h.

摘要

Hydrocracking process LOADS FROM THE METHOD Fischer-Tropsch IN WHICH A) Reacting HYDROGEN WITH CHARGE IN PRESENCE OF A CATALYST (1) in a first reaction zone comprising said catalyst (1) at least one matrix A BASE ALUMINA AND AT LEAST ONE COMPONENT HIDRODESHIDROGENACION. B) THE effluent from the first reaction zone is contacted with a catalyst (2) in a second reaction zone comprising said catalyst (2) 20 to 97% by weight of at least one matrix of at least one zeolite And in hydrogen form, said zeolite being characterized by a ratio MOLAR SiO 2 / SUPERIOR AL2O3 A 4.5; A sodium content less than 1% by weight determined on the zeolite CALCINED 1100 (DEGREES) C; A PARAMETER A0 CRYSTAL MESH ELEMENTAL LESS THAN 24,70.10-10M; A surface area determined by the method BET above 400 M2.G.-1. - at least one component of HIDRODESIDROGENACION.
