Abstract A catalytic composite comprising a combination of a nickel component, a molybdenum component and a platinum component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing, on an elemental basis, about 0.2 to about 0.5 percent by weight platinum. The key feature of the subject composite is the criticality of the platinum content of the composite. The principal utility of the subject composite is in the conversion of hydrocarbon feed stocks and in particular the hydrocracking of hydrocarbons. A specific example of the catalyst disclosed is a combination of nickel, molybdenum and platinum with a high silica faujasite-alumina carrier material containing 25 weight percent alumina in amounts sufficient to result in the composite containing, on an elemental basis, about 1 to about 15 weight percent nickel, about 1 to about 10 weight percent molybdenum and about 0.2 to about 0.5 weight percent platinum.
A catalytic composite comprising a combination of a nickel component, a molybdenum component and a platinum component with a zeolitic carrier material wherein said platinum component is present in an amount sufficient to result in the composite containing, on an elemental basis, about 0.2 to about 0.5 percent by weight platinum.
