  • Process for obtaining olefins from residual feedstocks
    Patent number: 6179993
    Abstract: A process for obtaining a substantial amount of olefinic products from a residual feedstock by use of a vapor short contact time conversion process unit comprised of a bed of fluidized heat transfer solids. The vapor short contact time process unit is operated at conditions which includes steam dilution to reduce partial pressure of hydrocarbon vapors and a vapor residence time less than about 0.5 seconds.
    Type: Grant
    Filed: February 21, 1997
    Date of Patent: January 30, 2001
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Noel M. Seimandi, Tony T. Cheng, Willibald Serrand, Mitchell Jacobson, Paul K. Ladwig, John F. Pagel, Michael R. Parrish, Hans A. Weisenberger
  • Dual process for obtaining olefins
    Patent number: 5952539
    Abstract: A process for producing normally gaseous olefins from two different process units sharing common downstream quench and fractionation facilities, wherein one of the process units is a short contact time mechanically fluidized vaporization unit for processing petroleum residual feedstocks and the other is a conventional steam cracking unit.

  • Integrated residua upgrading and fluid catalytic cracking
    Patent number: 5919352
    Abstract: A process wherein a residuum feedstock is upgraded in a short vapor contact time thermal process unit comprised of a horizontal moving bed of fluidized hot particles, then fed to a fluid catalytic cracking process unit. Hot flue gases from the fluid catalytic cracking unit is used to circulate solid particles and to provide process heat to the thermal process unit.

  • Process for deasphalting residua (HEN9511)
    Patent number: 5714056
    Abstract: A process for deasphalting a residua feedstock by use of a short vapor contact time thermal process unit comprised of a horizontal moving bed of fluidized hot particles. It is preferred that a mechanical means be used to fluidize a bed of hot particles.

  • Fluidized bed coking process
    Patent number: 5658455
    Abstract: An improved fluidized bed coking process wherein a residuum feedstock is introduced into a first stage comprised of a short vapor contact time reactor containing a horizontal moving bed of fluidized hot particles. Carbonaceous material is deposited onto the hot particles on contact with the hot particles, and a vapor product is produced. The hot particles, containing the carbonaceous deposits, are fed to a second stage fluidized bed coking process.
