Abstract: A method for disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure. The enclosure contains a plurality of stacked screens, the stacked screens have openings that decrease in size from a top of the stack to a bottom of the stack. The method also comprises introducing the mixture to an uppermost one of the plurality of stacked screens; moving the plurality of stacked screens to cause the oxidizable catalyst material to separate from and migrate to a location beneath the inert support media; conveying the separated inert support media to a location outside the enclosure for disposal as non-hazardous waste; and conveying the separated oxidizable catalyst material to a location outside the enclosure for at least one of reclamation, or thermal destruction.

Abstract: Supplemental heat required to raise the temperature of a regenerated catalyst to the minimum required to promote the catalyzed reaction in an FCC unit is provided by introducing adsorbent material containing HPNA compounds and HPNA precursors with the coked catalyst into the FCC catalyst regeneration unit for combustion. The HPNA compounds and HPNA precursors can be adsorbed on either a carbonaceous adsorbent, such as activated carbon, that is completely combustible and generates no ash, or on fresh or coked FCC catalyst that is recovered from an HPNA adsorption column that has treated the bottoms from a hydrocracking unit to remove the HPNA compounds and their precursors.

Abstract: Systems for separating a contaminant trapping additive from a cracking catalyst may include a contaminant removal vessel having one or more fluid connections for receiving contaminated cracking catalyst, contaminated contaminant trapping additive, fresh contaminant trapping additive, and a fluidizing gas. In the contaminant removal vessel, the spent catalyst may be contacted with contaminant trapping additive, which may have an average particle size and/or density greater than the cracking catalyst. A separator may be provided for separating an overhead stream from the contaminant removal vessel into a first stream comprising cracking catalyst and lifting gas and a second stream comprising contaminant trapping additive. A recycle line may be used for transferring contaminant trapping additive recovered in the second separator to the contaminant removal vessel, allowing contaminant trapping additive to accumulate in the contaminant removal vessel. A bottoms product line may provide for recovering contaminant trapping additive from the contaminant removal vessel.

Abstract: The microwave spent catalyst decoking method is a method for regenerating petrochemical catalysts by removing coke deposited in the catalyst using a 2.45 GHz microwave oven. The spent catalyst is heated in air or pure oxygen in the presence of a susceptor. The susceptor is made of silicon carbide-based composite material that absorbs 2.45 GHz microwave energy fast and efficiently. In one embodiment, the susceptor material is formed into pellets that are preferably four to five millimeters in diameter. The susceptor pellets are mixed with the spent catalyst and loaded into a thermally shielded refractory tube that rotates about its central axis. In a another embodiment, the apparatus is a thermally shielded tower or vertical tube made of refractory material that is transparent to microwave radiation and supports rows of susceptor rods that are aligned horizontally.

Abstract: Improved processing of spent catalyst from an oxygenate-containing feedstock to olefins conversion process is realized through the employment of a barrier filter to treat a catalyst particle-containing flue gas resulting from a catalyst regenerator. The barrier filter serves to separate the catalyst particles from the flue gas. Catalyst material so recovered can, with or without classifying, subsequently be appropriately recycled and further used.

Abstract: By continuously or intermittently adding amounts of magnetically active moieties, e.g. iron compounds, over time so that the moiety deposits on a catalyst or sorbent in a fluid catalytic cracker or similar circulating hydrocarbon conversion unit, older catalyst, being more magnetic, can be readily separated from catalyst which has been in the system a shorter time. Separation is readily accomplished by passing the catalyst and/or sorbent through a magnetic field and discarding the more magnetic 50% by wt. or more preferably 20% by wt., while recycling the remainder back to the hydrocarbon conversion unit.

Abstract: A process for demetallizing metals contaminated FCC catalyst in an FCC regenerator. A metals getter additive, with higher settling velocity, is added to the regenerator, to remove metals from FCC catalyst by solid-solid interaction. The FCC catalyst forms a light, discrete, dense phase fluidized bed on top of a fluidized bed of additive. FCC catalyst is recycled to the cracking reactor from the top fluidized bed, while additive can be withdrawn from the lower fluidized bed for disposal or for metals recovery and recycle. Additive can be optimized for metals removal and will not dilute the cracking catalyst in the FCC reactor.
