    Abstract: AN IMPROVEMENT IN A PROCESS WHEREIN A FIRST COMPOUND IS CONVERTED TO A SECOND COMPOUND IN AN ESSENTIALLY IRREVERSIBLE REACTION OR TO THE SECOND COMPOUND AND TO A THIRD COMPOUND IN ESSENTIALLY IRREVERSIBLE REACTIONS, THE SECOND COMPOUND AND THE THIRD COMPOUND ARE CONVERTIBLE TO EACH OTHER IN EQUILIBRIUM-LIMITED REACTIONS AND THE THIRD COMPOUND IS INITIALLY PRESENT IN THE REACTION ZONE IN AN AMOUNT GREATER THAN THE AMOUNT THAT WOULD BE PRESENT AT EQUILIBRIUM, WHICH INVOLVES INTRODUCING AN ADDITIONAL AMOUNT OF THE THIRD COMPOUND IN THE REACTION ZONE AND TERMINIATING THE PROCESS WHEN THE REACTION MIXTURE CONTAINS THE THIRD COMPOUND IN AN AMOUNT GREATER THAN THE AMOUNT INITIALLY PRESENT.

    Abstract: A process for regenerating a metal oxide sorbent used in the removal of arsenic from a gaseous hydrocarbon stream. The sorbent, usually copper oxide or lead oxide, is contacted with a stream of free molecular oxygen at low temperatures suitably in the range of 150* to 700*F. for a period of from about 2 to about 40 hours.

    Abstract: SULFUR-FREE, METHANE-RICH SUBSTITUTE NATURAL GAS IN PRODUCED FROM A HIGH SULFUR CRUDE OIL BY A NONPOLLUTING PROCESS CAPABLE OF ACHIEVING AN UNEXPECTEDLY HIGH TERMAL EFFCICENCY. THE PRROCESS COMPISES SEPARATING WHOLE CRUDE OIL INTO A PLURALITY OF FRACTIONS COMPRISING A BOTTOMS FRACTION AND A LIGHTER OIL FRACTION, DESULFURIZING AND HYDROCRACKING THE OIL FRACTION INTO A SUBSTANTIALLY SULFUR-FREE NAPHTHA IN THE PRESENCE OF HYDROGEN, WHICH IS PROVIDED BY CONVERTING A RESIDUE PORTION OBTAINED FROM THE BOTTOMS FRACTION. THE RESULTING SULFUR-FREE NAPHTHA IS COVERED INTO SUBSTITUTE NATURAL GAS IN THE PRESENCE OF STREAM. NOT ONLY IS A THERMAL EFFICIENCY OF APPROXIMATELY 100 PERCENT OBTAINED, NOTWITHSTANDING THE USE OF A PORTION OF THE CRUDE OIL FOR REFINERY FUEL, BUT NAPHTHA IS PRODUCED AT A VOLUMETRIC EFFICIENCY OF ABOUT 100 PERCENT BASED UPON THE CRUDE OIL FEEDSTOCK. THE SYSTEM IS AUTOGENIC WITH RESPECT TO HYDROGEN REQUIREMENTS FOR DESULFURIZATION, NITROGEN REMOVAL, AND HYDROCRACKING.

    Abstract: 1. IN A CONTINUOUS PROCESS FOR THE HYDROGENATION OF ACETYLENE TO ETHYLENE IN A CONVERSION ZONE; A METHOD OF CONTROL WHICH COMPRISES DETERMING THE CONCENTRATION OF HYDROGEN IN THE VAPOROUS EFFLUENT WITHDRAWN FROM SAID CONVERSION ZONE, ADJUSTING THE TEMPERATURE OF THE FEED MOIXTURE CONTAINING ACETYLENE, ETHYLENE AND HYDROGEN PASSED TO SAID CONVERSION ZONE RESPONSIVE TO SAID HYDROGEN CONCENTRATION, DETERMINING THE CONCENTRATION OF ACETYLENE IN SAID VAPOROUS EFFLUENT, AND ADJUSTING THE CONCENTRATION OF HYROGEN IN THE VAPOROUS FEED TO SAID CONVERSION ZONE RESPONSIVE TO SAID ACETYLENE CONCENRATION AND

    THE TRETEMPERATURE TO WHICH SAID VAPOROUS FEED IS TO BE HEATED RESPONSIVE TO SAID HYDROGEN CONCENTRATION.

    Abstract: A METHOD FOR CONTROLLING A HYDROGENATION PLANT TO AVOID LOCALIZED REACTOR HOT SPOTS AND TO AVOID REACTOR RUN-AWAY AND CATALYST DETERIORATION CAUSED THEREBY IS DISCLOSED FOR SUCH PLAANT INCLUDING A REACTOR AND CATALYST SYSTEM FOR PRODUCING A SATURATED HYDROCARBON FROM A CORRESPONDING UNSATURATED HYDROCARBON. THE METHOD COMPRISES THE STEPS OF SUPPLYING GASEOUS HYDROGEN AND LIQUID UNSATURATED HYDROCARBON FOR THE REACTOR AND CATALYST SYSTEM, SUPPLYING A RECYCLE PORTION OF A PRODUCT OF SAID SYSTEM INCLUDING SUCH SATURATED HYDROCARBON FOR THE INLET OF SAID REACTOR AND CATALYST SYSTEM, SUPPLYING AT LEAST THE LIQUID UNSATURATED HYDROCARBON AND ANY LIQUID PORTION OF SAID RECYCLE PORTION TO THE SYSTEM IN HEAT EXCHANGE RELATION WITH AN EFFLUENT STREAM OF THE SYSTEM, HEAT EXCHANGING THE UNSATURATED HYDROCARBON AND THE RECYCLE PORTION PRIOR TO INLETTING THE REACTOR SYSTEM AND CONTROLLING THE FLOW RATE THEREOF INTO SAID REACTOR SYSTEM SO THAT THE TEMPERATURE OF ALL MATERIALS ENTERING THE SYSTEM INCLUDING THE RECYCLE PORTION IS ABOVE THE DEW POINT OF THE MIXTURE COMPRISING THE TOTAL REACTOR

    FLUID, AND CONTROLLING THE TEMPERATURE OF THESE MATERIALS INCLUDING THE RECYCLE PORTION THROUGHOUT EVERY PORTION OF THE REACTOR AND CATALYST SYSTEM SO THAT THE TEMPERATURES REMAIN CONTINUALLY ABOVE THE DEW POINTS OF ALL OF THE MATERIALS AND THAT ALL MATERIALS ENTERING THE SYSTEM ARE MAINTAINED ENTIRELY IN THEIR GASEOUS PHASE UNIFORMLY THROUGHOUT THE SYSTEM.
