Abstract
Abstract An acidic multimetallic catalytic composite especially useful for the conversion of hydrocarbons comprises a combination of catalytically effective amounts of a platinum group component, a lanthanide series component, nickel component, and a halogen component with a porous carrier material. The platinum group, lanthanide series, nickel and halogen components are in the multimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % lanthanide series metal, about 0.05 to about 5 wt. % nickel, and about 0.1 to about 3.5 wt. % halogen. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group metal is present therein in the elemental metallic state, substantially all of the catalytically available nickel component is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions, or in a mixture of these states, while substantially all of the lanthanide series component is present in an oxidation state above that of the elemental metal.
