    摘要： A method for preparing an improved composition of matter whereby a solid catalyst comprising alumina derived from hydrous alumina predominating in alumina trihydrates and at least one platinum group component is used in hydrocarbon conversion service for a period of time to reduce the surface area of said solid catalyst to from about 20% to about 90% of the surface area of the original solid catalyst. This decreased area solid catalyst is treated with at least one metal promoter to produce a treated catalyst having improved properties. An improved method for hydrocarbon conversion using this treated catalyst is also disclosed.

    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 bismuth component, a cobalt component, and a halogen component with a porous carrier material. The platinum group component, bismuth 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. % bismuth, 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 in the preferred case substantially all of the bismuth is present therein in an oxidation state above that of the elemental metal. A specific example of the type of hydrocarbon conversion process disclosed in 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 DEACTIVATED HYDROCARBON CONVERSION CATALYST, WHICH IS A COMBINATION OF A PLATINUM GROUP COMPONENT, A RHENIUM COMPONENT, AND HALOGEN COMPONENT WITH A POROUS CARRIER MATERIAL AND WHICH HAS BEEN DEACTIVATED BY DEPOSITION OF CARBONACEOUS MATERIALS THEREON DURING A PREVIOUS CONTACTING WITH A HYDROCARBON CHARGE STOCK AT AN ELEVATED TEMPERATURE, IS REGENERATED BY THE SEQUENTIAL STEPS OF: (A) BURNING CARBON THEREFROM AT RELATIVELY LOW TEMPERATURE WITH A SUBSTANTIALLY SULFUR COMPOUND-FREE GAS STREAM CONTAINING H2O AND A RELATIVELY SMALL AMOUNT OF O2, (B) TREATING THE RESULTING PARTIALLY REGENERATED CATALYST AT A RELATIVELY HIGHER TEMPERATURE WITH A SUBSTANTIALLY SULFUR COMPOUND-FREE GAS STREAM CONTAINING A HALOGEN OR A HALOGEN-CONTAINING COMPOUND, H2O AND A RELATIVELY HIGHER AMOUNT OF O2, (C) PURGING O2 AND H2O FROM CONTACT WITH THE RESULTING CATALYST, AND (D) SUBJECTING THE RESULTING CATALYST TO CONTACT WITH A DRY AND SULFUR COMPOUND-FREE HYDROGEN STREAM. KEY FEATURES OF THE DISCLOSED METHOD ARE: (1) PRESENCE OF WATER IN THE GAS STREAMS USED IN ALL STEPS EXCEPT THE REDUCTION STEP; (2) CAREFUL CONTROL OF THE TEMPERATURE USED DURING EACH STEP; (3) ADJUSTMENT OF THE HALOGEN CONTENT OF THE CATALYST IMMEDIATELY AFTER THE CARBON-BURNING STEP AND PRIOR TO THE REDUCTION STEP; (4) CAREFUL CONTROL OVER THE COMPOSITION OF THE GAS STREAMS USED IN THE VARIOUS STEPS THEREOF; AND (5) EXCLUSION OF SULFUR COMPOUNDS FROM ALL GAS STREAMS UTILIZED.
