Abstract: A METHOD OF OPERATING A CONTINUOUS HYDROCARBON PROCESS EMPLOYING CATALYST PARTICLES WHEREIN CATALYST ACTIVITY IS MAINTAINE AT A PREDETERMINED LEVEL BY CONTINUOUS REGENERATION THEREOF WITHOUT REMOVAL OF ANY REACTOR FROM THE PROCESSING STREAMS. THE METHOD INCLUDES CONTINUOUS REDUCTION AND SULFIDING OF THE CATALYST PRIOR TO CONTACT WITH A REACTANT STREAM IN ONE OR MORE REACTORS IN WHICH A CONTINUOUS OR REASONABLY CONTINUOUS INPUT AND OUTPUT OF CATALYST IS REGULATED. THE SULFIDING AND REDUCTION STEPS TAKE PLACE IN AN UPPER PORTION OF A REACTION ZONE SO THAT THOSE STEPS OCCUR PRIOR TO CATALYST BEING CONTACTED WITH
A REACTANT PROCESSING STREAM. THE REGENERATION OF THE CATALYST IS CONTINUOUS AND INCLUDES A CARBON BURN-OFF AND REDUCTION AND SULFIDING STEP WHICH ALLOW THE CATALYST TO BE PASSED BACK INTO THE REACTOR SYSTEM THEREBY MAINTAINING CONTROLLED CATALYST ACTIVITY WITHIN THE REACTOR.-

Abstract: 1. A PROCESS FOR THE CONTINUOUS PREPARATION OF ETRAALKOXY GERMANIUM WHICH COMPRISES THE STEPS OF: (A) REACTING GERMANIUM WITH A HALOGEN OR A HALOGENCONTAINING COMPOUND IN A FIRST REACTION ZONE AT A TEMPERATURE IN THE RANGE OF ABOUT 71*C. TO ABOUT 104*C. AND A PRESSURE IN THE RANGE OF FROM ABOUT 1 ATMOSPHERE TO ABOUT 100 ATMOSPHERES, (B) SEPARATING UNREACTED HALOGEN OR HAOOGEN-CONTAINING COMPOUNDS FROM THE FIRST REACTION ZONE EFFLUENT TO PRODUCE A GERMANIUM TETRAHALIDE-CONTAININ FIRST LIQUID PHASE, (C) REACTING AT LEAST A PORTION OF THE SAID FIRST LIQUID PHASE IN A SECOND REACTION ZONE WITH A MONOHYDRIC ALKANOL AT A TEMPERATURE OF ABOUT 0=C. TO ABOUT 100*C. AND A PRESSURE IN THE RANGE OF ABOUT -1 ATMOSPHERE TO ABOUT 100. ATOMSPHERES IN ORDER TO PRODUCE A SECOND LIQUID PHASE, AND (D) SEPARATING THE RESULTANT SECOND REACTION ZNE EFFLUENT IN A SECOND SEPARATION ZONE TO PRODUCE A TETRAALKOXY GERMANIUM-CONTAINING LIQUID PHASE AND A HYDROGEN HALIDE-CONTAINING LIQUID PHASE AND A HYERING SAID TETRAALKOXY GERMANIUM LIQUID PHASE.

Abstract: A METHOD OF OPERATING A REFORMING PROCESS EMPLOYING A PLATINUM GROUP METAL CATALYST. A MULTIPLE REACTOR SYSTEM COMPRISING THE SIDE-BY-SIDE REACTORS IS EMPLOYED, EACH REACTOR CONTAINING A DENSE-PHASE MOVING CATALYST BED. THE METHOD OF THIS INVENTION ENABLES PROCESSING OF THE CATALYST THROUGH THE REACTOR SYSTEM IN SERIES FLOW, ALL REACTORS REMAINING ON STREAM AT REFORMING CONDITIONS. THE METHOD PROVIDES FOR RELATIVELY FREQUENT REGENERATION, AND CATALYST ACTIVITY IS MAINTAINED AT A PREDETERMINED HIGH LEVEL WITHOUT RESORT TO INCREASINGLY SEVERE REFORMING CONDITIONS.

Abstract: Trace amounts of platinum, otherwise lost, are recovered from the alum solution resulting from the digestion of spent aluminabased platinum catalyst in sulfuric acid. The alum solution is commingled with a normally liquid trialkyl phosphate and a platinum-containing residue forms at the interface of said liquids as they are allowed to settle out into an upper and lower liquid phase.
Abstract translation: 从在氧化铝基铂催化剂在硫酸中的消解产生的明矾溶液中回收痕量的铂，否则损失。 明矾溶液与正常液体的三烷基磷酸盐混合，并且在所述液体的界面处形成含铂的残余物，因为它们可以沉降到上部和下部液相中。

Abstract: A CATALYST COMPOSITION CHARACTERIZED BY A METHOD OF MANUFACTURE. THE CATALYST COMPOSITION COMPRISES A PLATINUM GROUP METAL, GERMANIUM, AND AN ALKALI METAL COMPOSITED WITH AN ALUMINA CARRIER MATERIAL. THE ALUMINA CARRIER MATERIAL IS IMPREGNATED WITH THE CATALYTIC COMPONENTS, STEAM TREATED AT OXIDIZING CONDITIONS INCLUDING A TEMPERATURE OF FROM ABOUT 400* TO ABOUT 1200*F., AND FURTHER TREATED IN A SUBSTANTIALLY DRY ATMOSPHERE AT OXIDIZING CONDITIONS INCLUDING A TEMPERATURE OF FROM ABOUT 400* TO ABOUT 1200*F., TO YIELD A PRODUCT CHARACTERIZED BY A LOI AT 900*C. OF LESS THAN ABOUT 1 WT. PERCENT PRIOR TO REDUCTION AND SULFIDING.

Abstract: A METHOD OF OPERATING A CONTINUOUS REFORMING-REGENERATION PROCESS EMPLOYING A HALOGEN-CONTAINING PLATINUM CATALYST PREFERABLY COMPRISING ONE OR MORE PROMOTER METALS WHEREIN CATALYST ACTIVITY IS MAINTAINED AT A PREDETERMINED LEVEL BY CONTINUOUS REGENERATION THEREOF WITHOUT OF REMOVAL OF ANY REACTOR FROM THE PROCESS STREAM. THE METHOD INCLUDES THE CONTINUOUS REDUCTION AND SULFIDING OF THE CATALYST PRIOR TO CONTACT WITH THE REACTANT STREAM, THE REDUCTION AND SULFIDING BEING EFFECTED IN A CONFINED ZONE IN INDIRECT HEAT EXCHANGE RELATIONSHIP WITH THE PREHEATED REACTANT STREAM CHARGED TO THE REFORMING PROCESS.
