| titleOfInvention | Hydrocracking catalyst for the production of middle distillates containing a stabilized y zeolite and a bridged clay as basic constituents |
| abstract | PRECISION OF DISCLOSURE The invention relates to a catalyst containing weight: a) about 1 to 70% of a bridged clay belonging to the group of smectites, whose spacing of the sheets is maintained by the presence of shims made of oxides of at least one of the following: boron, magnesium, aluminum, phosphorus, silicon, titanium, chromium, zirconium, molybdenum, tungsten; b) about 1 to 70% of a zeolite stabilized type Y acid - SiO2 / Al2O3 molar ratio about 8 to 70, - sodium content less than 0.15% by weight determined on the zeolite calcined at 1100 ° C, - of parameter ao of the elementary mesh ranging between 24.55x10-10m and 24.24x10-10m, - CNa recovery capacity in sodium ions, expressed in grams of sodium per 100 grams of modified, neutralized and calcined zeolite greater than approximately 0.85, - specific surface greater than approximately 400 m2.g-1, - adsorption capacity water vapor at 25 ° C greater than about 6% by weight (at a P / Po ratio equal to 0.10), - porous distribution comprising between 1 and 20% of the pore volume contained in diameter pores between 20x10-10m and 80x10-10m, the rest of the pore volume being essentially contained in pores of diameter less than 20x10-10m; c) about 5 to 97% of an amorphous matrix consisting of free alumina type .gamma.,?, .delta. or .theta., or mixtures of these or alumina associated with at least one of the oxides of the elements following: boron, magnesium, silicon, phosphorus, calcium, titanium, vanadium, chromium, manganese, iron, gallium, yttrium, zirconium, tin, lanthanum, cerium, praseodymium, neodymium; d) at least one metal or a metal compound chosen from the group consisting of the noble or non-noble metals of group VIII of the periodic table, concentration of group VIII noble metals or metals, expressed by weight of this or these metals, being between 0.01 and 5%, the concentration of metal or non-noble metals of group VIII, expressed by weight of this or these metals, being between 0.01 and 15%. This catalyst is useful for hydrocracking petroleum fractions. The invention also relates to a method for using this catalyst. |
