Definitions

  • a prior art process for removal of sulfur dioxide from FCC flue gas highly pertinent to the present invention is that dis­closed in U.S. Patent 4,071,436 to Blanton, Jr., et al.
  • alumina particles are in admixture with the FCC catalyst and are circulated therewith throughout the reactor-regenerator circuit.
  • the regenerator the alumina reacts with sulfur dioxide to form a solid compound, which when circulated to the reactor reacts with hydrocarbons in the feedstock in the reducing environment to release the sulfur, supposedly as hydrogen sulfide.
  • the sulfur is thereby dealt with in the FCC facilities downstream of the reactor section instead of as part of the regenerator flue gas.
  • This reference states that it is preferred that materials such as calcium not be present in the particulate solid used for removal of the sulfur dioxide, since they simply form a noncyclical sulfur-containing solid.
