Abstract: Disclosed is a catalyst comprising a zeolite comprising a framework, the framework comprising silicon and aluminum, and a noble metal. The zeolite has undergone at least a first exchange with a Group I or II cation or ammonium and thereafter is contacted with a second Group I or II cation. The step of contacting comprises an exchange, incipient wetness, or dry impregnation. The noble metal is deposited at the zeolite.

Abstract: A method for preparing a hydrocracking catalyst comprising: (i) providing a shaped body comprising a zeolite and a binder, wherein the shaped body has been obtained by shaping, calcination and cooling, wherein the zeolite is ZSM-5 having a silica (SiO2) to alumina (Al2O3) molar ratio of 25-75; (ii) optionally drying the shaped body at a temperature of 100-300° C. for a period of at least 1 hour; (iii) depositing a hydrogenation metal on the shaped body by an impregnation for a period of at most 2 hours such that the amount of the hydrogenation metal is 0.010-0.30 wt % with respect to the total catalyst; (iv) optionally rinsing the metal deposited shaped body with water; and (v) heat-treating the metal deposited shaped body in air at a temperature of 250-300° C. for a period of 1-5 hours; wherein the catalyst comprises a total of less than 0.05 wt % sodium and cesium.
