Abstract: A PROCESS FOR HYDROGENATING BENZENE IN THE VAPOR PHASE WITH MOLECULAR HYDROGEN IN A REACTION ZNE IN THE PRESENCE OF DILUENT CYCLOHEXANE VAPOR AND A HYDROGENATION CATALYST WHEREIN A PORTION OF THE HEAT OF REACTION IS ABSORBED FROM THE REACTION ZONE BY INDIRECT HEAT TRANSFER MEANS INTO A CIRCULATING LIQUID STREAM COMPRISING CYCLOHEXANE AND BENZENE AND WHEREIN SUCH HEATED CIRCULATING LIQUID STREAM IS CONTACTED WITH A MOLECULAR HYDROGEN CONTAINING GAS TO FORM A VAPORIZED REACTION CHARGE MIXTURE COMPRISING BENZENE, HYDROGEN AND DILUENT CYCLOHEXANE. REACTION ZONE TEMPERATURES ARE MAINTAINED WITHIN A DESIRABLE OPERATING RANGE BY ABSORBING HEAT FROM THE REACTION ZONE INTO THE CIRCULATING LIQUID STREAM AND SUCH ABSORBED HEAT IS SUBSEQUENTIALLY UTILIZED TO VAPORIZE THE BENZENE AND CYCLOHEXANE COMPONENTS OF THE REACTION CHARGE MIXTURE AND TO PREHEAT THE REACTION CHARGE MIXTURE TO THE DESIRED REACTION INLET TEMPERATURE.

Abstract: A VERTICAL DOWNFLOW REACTOR FOR CONTACTING A TWO-PHASE, VAPOR-LIQUID REACTION MIXTURE WITH SOLID CATALYST CONTAINED IN ONE OR MORE REACTOR VESSEL CATALYST ZONES. MEANS ARE PROVIDED IN THE UPPER PORTION OF SUCH VERTICAL RACTOR TO SEPARATE ANY SOLID PARTICULATE CONTAMINANTS FROM SAID REACTION MIXTURE PRIOR TO ADMITTING THE REACTION MIXTURE INTO A REACTOR VESSEL CATALYST ZONE. MEANS ARE ALSO PROVIDED FOR EVENLY DISTRIBUTING VAPOR AND LIQUID COMPONENTS OF THE REACTION CHARGE MIXTURE ACROSS THE HORIZONTAL CROSSSECTIONAL AREA OF A REACTOR VESSEL CATALYST ZONE.

Abstract: EFFFLUENTS FROM A FIRST CATALYST ZONE AND QUENCH FLUID TO FROM A NEW TWO-PHASE VAPOR-LIQUID REACTION MIXTURE AND REACTOR INTERNAL PARTS FOR EVELY REDISTRIBUTING THE NEW REACTION MIXTURE ACROSS THE TOP HORIZONTAL CROSS-SECTION OF A SECOND CATALYST ZONE.

A VERTICAL, DOWNFLOW REACTOR FOR CONTACTING A TWO-PHASE VAPOR-LIQUID REACTION MIXTURE WITH SOLID CATALYST CONTAINED IN TWO OR MORE REACTOR VESSEL CATALYST ZONESS, WHEREIN SUCH REACTOR HAS MEANS FOR INJECTING QUENCH FLUID BETWEEN SUCCEEDING CATALYST ZONES. SUCH REACTOR COMPRISES REACTOR INTERNAL PARTS LOCATED INTERMEDIATE TO TWO CATALYST ZONES FOR INTIMATELY MIXING VAPOR AND LIQUID REACTION

Abstract: A PROCESS FOR REGENERATING A BED OF COKE-CONTAINING CRYSTALLINE ZEOLITIC MOLECULAR SIEVES BY CONTINUOUSLY PASSING A CLOSED-LOOP FLOW OF HOT, OXYGEN-CONTAINING INERT GAS THROUGH THE MOLECULAR SEIVE BED, WHEREIN WATER IN THE CIRCULATING GAS STREAM IS MAINTAINED BELOW A PRESELECTED CONCENTRATION.
