    摘要: An improvement in gasoline octane without substantial decrease in overall yield is obtained in an integrated process combining a fluidized catalytic cracking reaction and a fluidized catalyst olefin oligomerization reaction when crystalline medium pore shape selective zeolite catalyst particles are withdrawn in partially deactivated form from the oligomerization reaction stage and added as part of the active catalyst in the FCC reaction.

    摘要: A process and apparatus for controlling the flow of FCC catalyst around a catalyst regenerator, using a non-mechanical valve, is disclosed. The preferred non-mechanical valve provides a de-aeration section, addition of fluidizing gas, a "U" trap seal, and venturi gas outlet on the top of the trap, for reliable flow control of non-uniform settling particles such as FCC catalyst. Control of the flow of a fluidizing gas to such a valve changes the flow properties of the FCC catalyst and permits flow control without resort to plug valves, or other internal mechanical valves, which are difficult to use in the harsh environment experienced within FCC regenerators.

    摘要: A known method for passivating contaminant metals on an FCC catalyst comprises treating the catalyst with a sufficient amount of a sulfur-containing compound capable of associating with the contaminant metals when in contact therewith. An improvement comprises contacting the catalyst with the sulfur-containing compound for at least 3 seconds. In another embodiment of the invention, the improvement comprises contacting the catalyst with the sulfur-containing compound in a separate treatment vessel.

    摘要: Addition of a CO combustion promoter to a circulating fluid bed (CFB) combustion unit and reduction of the air addition rate to 100-110% of stoichiometric improves the efficiency of CO burning, reduces emissions of CO and improves the efficiency of the unit. Stable, reduced temperature operation with air rates close to stoichiometric, reduces NO.sub.x emissions. A circulating (100-400 micron particles) or fast settling (400-1200 micron particle) CO combustion promoter may be used.

    摘要: Addition of a readily fluidizable, but fast settling, 400-1200 micron average diameter particulate CO combustion promoter to a circulating fluid bed (CFB) combustion unit improves the efficiency of CO burning, reduces emissions of CO and improves the efficiency of the unit. The CO combustion promoter accumulates in, or just above, in the fast fluidized bed combustion zone of the CFB.
