    摘要： A HALOGENATED REFORMING CATALYST COMPRISING PLATINUM WHICH HAS BECOME DEACTIVATED WITH CARBONACEOUS DEPOSITS DURING ON-STREAM REFORMING IS REGENERATED BY THE COMBINATION OF (1) REMOVING CARBONACEOUS MATERIAL BY BURNING WITH AN OXYGEN CONTAINING GAS UNDER CONDITIONS TO AVOID HEAT DAMAGE TO THE CATALYST, (2) HEATING THE CATALYST ITH AIR TO A TEMPERATURE OF ABOUT 900*F, (3) SELECTIVELY CHLORINATING EACH CATALYST BED WITH A MOISTURE SATURATED AIR STREAM TO A PREDETERMINED CHLORIDE LEVEL, (4) REDUCING THE CHLORIDED CATALYST WITH HYDROGEN RICH GAS FOR A PERIOD OF TIME IN THE RANGE OF 1 TO 4 HOURS, (5) ADDING SULFUR TO EACH CATALYST BED THEROETICALLY SUFFICIENT TO SULFIDE THE PLATINUM COMPONENT OF THE CATALYST AND (6) INITIATING ON-STREAM REFORMING OF NAPHTHA IN THE PRESENCE OF ADDED HYDROGEN SULFIDE.

    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.

    摘要： THE ACTIVITY AND STABILITY OF A DEACTIVATED REFORMING CATALYST CONTAINING A PLATINUM GROUP METAL AND GERMANIUM ARE RESTORED TO THAT OF FRESH CATALYST BY (1) REMOVING SUBSTANTIALLY ALL CARBON FROM THE CATALYST; (2) CONTACTING THE CATALYST AT ABOUT 900*F. WITH A NONREDUCING GAS CONTAINING HALOGEN, STEAM AND OXYGEN UNTIL ABOUT 85% W. OF THE DESIRED HALIDE CONTENT IS ADDED; (3) DISCONTINUING THE USE OF STREAM AND OXYGEN FROM THE LASTMENTIONED STEP UNTIL THE HALOGENATION IS COMPLETED; AND (4) DRYING AND REDUCING THE CATALYST WITH A HYDROGENCONTAINING GAS; THEN REUSING THE CATALYST IN A REFORMING PROCESS. PEFERABLY, THE CATALYST IS HLOGENATED TO A LEVEL ABOUT 20% GREATER THAN THAT OF FRESH CATALYST. IT IS ALSO PREFERRED THAT THE CATALYST THEN BE DRIED WITH A NONREDUCING GAS AT ABOUT 900*F. UNTIL THE WATER CONTENT IN THE EXIT GAS IS BELOW 150 P.P.M.V. FOLLOWED BY REDUCING AT LEAST THE PLATINUM OXIDES OR CHLORIDES BY CONTACT WITH A HYDROGEN-CONTAINING GAS AT 700-900*F. THE REGENERATION PROCEDURE IS EPECIALLY APPLICABLE TO PLATINUM-GERMANIUM CATALYSTS USED IN HIGH SEVERITYFULLY-REGENERATIVE REFORMING PROCESSES.

    摘要： A TWO-STAGE HYDROCRACKING PROCESS EMPLOYING RECYCLE OF HIGH BOILING, SECOND STAGE PRODUCT TO SECOND STAGE FEED AND A SECOND STAGE CATALYST CONTAINING AN IRON GROUP HYDROGENATIVE METAL SUPPORTED ON AN AMORPHOUS SILICAALUMINA-FLUORINE ACID-ACTING BASE ISIMPROVED TO AVOID FORMATION OF POLYAROMATIC COMPOUNDS IN THE HIGH BOILING PRODUCT BY (A) FIRST DISCONTINUING THE FLOW OF HYDROCARBON FEED TO THE SECOND-STAGE, (B) THEN CONTACTING THE SECOND STAGE CATALYST WITH OXYGEN, (C) CONTACTING THE OXIDIZED SECOND STAGE CATALYST WITH A SULFIDING COMPOUND AT CONDITIONS TO CONVERT THE IRON GROUP METAL COMPONENT TO A SULFIDE FORM, (D) CONTACTING THE SECOND STAGE CATALYST WITH FROM ABOUT 0.001% TO ABOUT 0.2 WT. OF CATALYST OF FLUORINE IN THE FORM OF A VAPOR PHASE FLUORIDING COMPOUND AT A TEMPERATURE OF FROM 350* TO 1100*F., AND (E) RE-ESTABLISHING THE FLOW OF HYDROCARBON FEED TO THE SECOND-STAGE.
