摘要： A process and apparatus for increasing the coke burning capacity of FCC catalyst regenerators is disclosed. An auxiliary regenerator receives spent catalyst from an FCC stripper and burns some of the coke at turbulent or fast fluidized bed conditions. Partially regenerated catalyst and flue gas enter a low pressure drop cyclone discharging more than 90% of the partially regenerated catalyst down into a bubbling or fast fluidized bed in the primary regenerator. Flue gas from the auxiliary regenerator is discharged into the dilute phase above the bed in the primary regenerator. Catalyst entrainment from the fluidized bed in the primary regenerator may be reduced because less combustion air is needed as a result of partial regeneration in the auxiliary regenerator. Reduced NOx and dust emissions, and/or increased coke burning capacity, may be achieved, especially when a bubbling dense bed primary catalyst regenerator is used.
摘要翻译：公开了一种用于提高FCC催化剂再生器的焦炭燃烧能力的方法和装置。辅助蓄热器从FCC汽提塔接收废催化剂，并在湍流或快速流化床条件下燃烧一些焦炭。部分再生的催化剂和烟道气进入低压降旋风分离器，将部分再生催化剂的90％以上排放到主再生器中的起泡或快速流化床中。来自辅助再生器的烟气被排放到主再生器床上方的稀相中。由于在辅助再生器中部分再生，需要较少的燃烧空气，所以可以减少主要再生器中来自流化床的催化剂夹带。特别是当使用起泡致密床一次催化剂再生器时，可以实现降低NOx和粉尘排放和/或增加焦炭燃烧能力。

摘要： A process for multistage regeneration of spent FCC catalyst in an "Orthoflow" or stacked FCC unit having a stripper mounted over the regenerator. Spent catalyst is discharged into a fast fluidized bed coke combustor heated by direct contact heat exchange with catalyst and large particles or beads of CO combustion promoter. The large particle CO combustion promoter is trapped in the coke combustor, to permit complete CO combustion, with limited coke combustion.

摘要： A process and apparatus for simultaneously heating and cooling of spent FCC catalyst during regeneration in a high efficiency FCC regenerator, one using a fast fluidized bed coke combustor. The coke combustor burns coke from spent catalyst in a turbulent or fast fluidized bed, and discharges catalyst and flue gas up into a dilute phase transport riser. Catalyst is separated into flue gas and a bubbling dense bed of catalyst. The coke combustor is heated by recycling hot catalyst from the bubbling dense bed and simultaneously cooled by a backmixed heat exchanger. Catalyst flows from the combustor to the cooler and is displaced back into the combustor by adding air to the catalyst in the cooler. Heating promotes rapid coke combustion, while cooling reduces thermal and hydrothermal deactivation of the spent catalyst. High superficial vapor velocities in the cooler promote heat transfer without disrupting flow in the fast fluidized bed coke combustor and without increasing catalyst traffic in the flue gas above the bubbling dense bed.

摘要： An improved process for upgrading paraffinic naphtha to high octane fuel by contacting a naphtha feedstock, such as virgin naphtha feedstock stream containing predominantly C.sub.7 -C.sub.12 alkanes and naphthenes, with solid medium pore acid zeolite cracking catalyst under low pressure selective cracking conditions effective to produce at least 10 wt % selectivity C.sub.4 -C.sub.5 isoalkene. Cracking effluent is separated to obtain a light olefinic fraction rich in C.sub.4 -C.sub.5 isoalkene and a C.sub.6 + liquid fraction of enhanced octane value containing less than 50 wt % aromatic hydrocarbons. In a multistage operation enhanced octane products are obtained by etherifying the isoalkene fraction and by contacting the C.sub.6 + normally liquid fraction with reforming catalyst under moderate reforming conditions at elevated temperature to obtain a reformate product of enhanced octane value.

摘要： A process and apparatus for controlled, multi-stage regeneration of FCC catalyst is disclosed. A modified high efficiency catalyst regenerator, with a fast fluidized bed coke combustor, dilute phase transport riser, and second fluidized bed regenerates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor. Second stage catalyst regeneration occurs in the second fluidized bed. The amount of combustion air added to both regeneration stages is set to maintain partial CO combustion in both stages. Controlled multi-stage regeneration reduces the steaming or deactivation of catalyst during regeneration, maximizes coke burning capacity of the regenerator, and minimizes or eliminates NOx emissions.

A modified high efficiency catalyst regenerator, with a fast fluidized bed coke combustor, dilute phase transport riser, and second fluidized bed regenerates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor. Second stage catalyst regeneration occurs in the second fluidized bed. The amount of combustion air added to, and conditions in, the coke combustor are controlled to limit CO combustion, while the second stage of regeneration, in the second fluidized bed, achieves complete CO combustion. Controlled multi-stage regeneration reduces steaming or deactivation of catalyst during regeneration, increase coke burning capacity, and reduces NOx emissions.

摘要： A process and apparatus are disclosed for achieving turbulent or fast fluidized bed regeneration of spent FCC catalyst in a bubbling bed regenerator having a stripper mounted over the regenerator and a stripped catalyst standpipe within the regenerator. A closed coke combustor vessel is added alongside an existing regenerator vessel, and spent catalyst is discharged into a transfer pot beneath the existing dense bed, then into the coke combustor. Catalyst is regenerated in a turbulent or fast fluidized bed, and discharged into the dilute phase region above the existing bubbling dense bed. The discharge line preferably encompasses, and is in a heat exchange relationship with, the spent catalyst standpipe. Discharge catalyst is collected in the bubbling dense bed surrounding the coke combustor, and may be given an additional stage of regeneration. Catalyst may be recycled from the dense bed to the transfer pot.

Each stage preferably has a successively higher temperature, and flue gas is removed after each stage. The process may regenerate a single phase catalyst or, preferably, a dual phase catalyst system, wherein an intermediate pore zeolite catalyst contained within a less elutriatable catalyst particle and a larger pore zeolite catalyst contained within a more elutriatable catalyst particle, thereby separating the intermediate pore zeolite catalysts from the larger pore zeolite catalysts prior to a final regeneration step.
