    摘要: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with an acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a lanthanide series component, a cobalt component, and a halogen component with a porous carrier material. The platinum group component, lanthanide series component, cobalt component, and halogen component are present 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 component, about 0.05 to about 5 wt. % cobalt, 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 cobalt 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 therein in an oxidation state above that of the elemental metal. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the acidic multimetallic catalyst disclosed herein at reforming conditions.

    摘要: A process for the preparation of an ammonia synthesis catalyst, in which an iron oxide, together with traces of aluminum, calcium, potassium, magnesium and silicon oxides, is fused in the presence of a small quantity of graphite and reduced and the reduced catalyst is thereafter treated with an aqueous solution of a water soluble cerium salt.The use of the so prepared catalyst in the synthesis of ammonia makes it possible to operate at significantly reduced temperatures and/or pressure, and thereby obtain very considerable capital and operational savings.
