Abstract: APPARATUS FOR EFFECTING REGENERATION OF CATALYST MATERIAL IN A FLUID CATALYTIC CRACKING PROCESS. IN THE LATTER MENTIONED PROCESS, A HYDROCARBON MATERIAL IS CONTACTED WITH FLUIDIZED SOLID CATALYST WITHIN A REACTION ZONE WHEREBY TO EFFECT CONVERSION OF AT LEAST A PORTION OF SAID HYDROCARBON MATERIAL TO A DESIRED CONVERSION PRODUCT, SIMULTANEOUSLY, THE CATALYST IS AFFECTED BY THE DEPOSITION OF A LAYER OF COKE ON OR ABOUT THE OUTER SURFACE THEREOF. THE INVENTION RELATS SPECIFICALLY TO AN APPARATUS FOR REGENERATING THE FLUIDIZED CATALYST FOR REUSE, WHEREIN PARTICLES OF THE LATTER ARE TRANSPORTED THROUGH AN ELONGATED REACTION FLOW PATH. THE REACTION ACHIEVED IN THE REGENERATING CHAMBER CAUSES THE COKE TO BE BURNED FROM THE CATALYST IN A COMBUSTION SUPPORTING ATMOSPHERE PROVIDED BY A UNIFORM AIR FLOW INTRODUCED AT THE CHAMBER LOWER END IN A MANNER TO AVOID FLOW DISCONTINUITIES AND DISTURBANCES TO THE DESIRED AIR STREAM.

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
