Patent ID: 8758598

Claim:
Process for selective preparation of middle distillates by selective conversion of a hydrocarbon containing feedstock under hydrocracking conditions with a hydrocarbon conversion catalyst comprising one or more hydrogenation components supported on a support comprising a beta zeolite and an amorphous inorganic oxide, the beta zeolite having undergone the process step of being modified to an Ion Exchange Capacity of 630 to 5630 wtppm sodium and having a SiO 2 :Al 2 O 3 molar ratio of at least 50 and a surface area as measured by BET of 400-800 m 2 /g, the amorphous inorganic oxide selected from the group consisting of silica-alumina, alumina and combinations thereof, the support having an Ion Exchange Capacity-Acidity Index of less than 3.7, the support comprising less than 30 wt % zeolite beta, and the hydrogenation component consisting of Group VIII and/or Group VI B elements.
