Abstract: A HYDRODESULFURIZATION PROCESS FOR TREATING A SULFUR CONTAINING GAS-OIL HYDROCARBON CHARGE TO YIELD A LOWSULFUR GAS-OIL PRODUCT AND A NAPHTHA PRODUCT WHEREIN EFFLUENT FROM A HYDRODESULFURIZATION PROCESS COMPRISING GAS-OIL, NAPHTHA, HYDROGEN AND HYDROGEN SULFIDE IS SEPARATED INTO A LIQUID FRACTION AND A VAPOR FRACTION, WHEREIN THE VAPOR FRACTION IS TREATED TO YIELD A TREATED HYDROGEN STREAM SUBSTANTIALLY FREE OF HYDROGEN SULFIDE, WHEREIN RECYCLE, NAPHTHA IS COMBINED WITH THE LIQUID FRACTION TO FORM A MIXTURE HAVING A BUBBLE POINT TEMPERATURE BELOW ABOUT 650*F. AT A PRESSURE OF ABOUT 130 P.S.I.G., WHEREIN THE LIQUID MIXTURE IS STRIPPED IN A STRIPPING ZONE TO REMOVE HYDROGEN SULFIDE EMPLOYING TREATED HYDROGEN AS STRIPPING VAPOR AT A PRESSURE OF ABOUT 100-130 P.S.I.G. AT THE BUBBLE POINT TEMPERATURE OF THE LIQUID MIXTURE, WHEREIN STRIPPED LIQUID SUBSTANTIALLY FREE O HYDROGEN SULFIDE IS FRACTIONATED INTO A NAPHTHA FRACTION AND A GAS-OIL FRACTION, AND WHEREIN A PORTION OF THE NAPHTHA FRACTION IS RECYCLED FOR MIXTURE WITH ADDITIONAL LIQUID FRACTION FROM THE HYDRODESULFURIZATION REACTION.

Abstract: An apparatus for fluid catalytic cracking of hydrocarbons including an elongated confined reaction conduit comprising an elongated riser having catalyst and hydrocarbon introduction means at the lower end thereof, a flow reversal means connected to the upper end of said riser for reversing the flow direction of catalyst and hydrocarbons exiting said riser, and a downcomer forming an annular space around an upper portion of said riser for receiving catalyst and hydrocarbons from said flow reversal means and conveying them downward into a reaction vessel. Reaction methods and process conditions are given for use with the disclosed apparatus.
