Definitions

  • the desired low pour point fuel oil is recovered as the bottoms with the tower overhead of about 204°C (400°F ) hydrocarbons comprising C 4 and lighter gaseous products plus hydrocarbons in the gasoline boiling range.
  • the combination process of this U.S. patent is practiced in two complete processing units, a catalytic cracker with all its usual attendant equipment including a fractionator and a catalytic hydrodewaxer with its usual attendant equipment including a fractionator. Thus, these units may be operated in combination or separately in a blocked-out operation.
  • the present invention relates to a process for reducing the pour point of a middle distillate, particularly a middle distillate boiling in the range of 160° to 427°C (320° to 800°F).
  • this invention may be described as an improvement to the combination process of U.S. Patent No. 3,891,540 wherein the catalytic cracking unit and the catalytic dewaxing unit utilize a common fractionator and middle distillate stripper while providing substantially the same dewaxed fuel oil product obtained in the process of U.S. Patent No. 3,891,540. Describing this invention in accordance with the process of U.S. Patent No.
  • a catalytic dewaxing function can be incorporated into a catalytic cracking unit at a substantially reduced investment and at a substantially reduced operating cost as compared to blocked-out operations of catalytic cracking and catalytic dewaxing.
  • a self-contained and self-sufficient catalytic dewaxing unit would require its own product fractionator and stripper when practicing the present invention
  • the operations performed by such equipment can be performed by similar equipment in the catalytic cracking unit. This is achieved, for example, by not passing the light cycle oil sidestream, drawn off the catalytic cracker main fractionator, to the catalytic cracker stripper but rather sending it directly to the catalytic dewaxing unit as the feedstream thereto.
  • the dewaxing catalysts of this invention may be in the hydrogen form which is the preferred form, or they may be base exchanged or impregnated to contain ammonium or a metal cation complement. It is desirable to calcine the catalyst after base exchange.
  • the metal cations that may be present include any of the metals of Groups I through VII of the Periodic Table. However, in the case of Group IA metals, the cation content should in no case be so large as to effectively inactivate the catalyst. For example, a completely sodium exchanged H-ZSM-5 is not operative in the present invention.
