摘要： Oxides of nitrogen (NO.sub.x) emissions from an FCC regenerator are reduced by operating the regenerator in partial CO burn mode to produce flue gas with more CO than O.sub.2 and with NO.sub.x precursors. This flue gas is then enriched with controlled amounts of oxygen and charged over catalyst, preferably Group VIII noble metal on a support, to convert most NO.sub.x precursors to nitrogen. Flue gas may then be charged to a CO boiler. Eliminating more than 90% of NO.sub.x emissions is possible by operating the FCC regenerator in partial CO burn mode, then adding air and catalytically converting NO.sub.x precursors at substoichiometric conditions. Conversion of NO.sub.x, if formed in the regenerator, may be achieved as well.
摘要翻译：通过在部分CO燃烧模式下操作再生器来减少来自FCC再生器的氮（NOx）排放的氧化物，以产生具有比O 2和NO x前体更多的CO的烟道气。然后，该烟道气用受控量的氧气富集，并通过催化剂，优选载体上的VIII族贵金属加入，以将大部分NOx前体转化为氮气。然后将烟道气充入CO锅炉。通过在部分CO燃烧模式下操作FCC再生器，然后在亚化学计量条件下添加空气和催化转化NOx前体，可以消除超过90％的NOx排放。也可以在再生器中形成NOx的转化。

摘要： Oxides of nitrogen (NO.sub.x) emissions from FCC regenerators in complete CO combustion mode are reduced by degrading regenerator performance to increase the coke on regenerated catalyst. High zeolite content cracking catalyst, regenerated to contain more coke, gives efficient conversion of feed and reduces NO.sub.x emissions from the regenerator. Operating with less catalyst, e.g., 30-60% of the normal amount of catalyst in the bubbling dense bed, can eliminate most NO.sub.x emissions while increasing slightly plant capacity and reducing catalyst deactivation.
摘要翻译：通过降低再生器的性能，增加再生催化剂上的焦炭，可以降低FCC再生器在完全CO燃烧模式下的氮氧化物（NOx）排放。再生含有更多焦炭的高沸石含量裂化催化剂能够有效地转化进料并减少再生器的NOx排放。以较少的催化剂操作，例如起泡致密床中正常量的催化剂的30-60％可以消除大部分NOx排放物，同时增加轻微的装置容量并减少催化剂失活。

摘要： 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 FCC catalyst is recycled to the cracking reactor from the top fluidized bed, while additive can be withdrawn from the lower fluidized bed for disposal or for metals recovery and recycle.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.

摘要： A process for fluidized catalytic cracking of heavy feed using a low H.sub.2 S content lift gas in the base of a riser reactor. The lift gas is a recycled, ethylene rich stream obtained by removing H.sub.2 S from a compressed vapor stream intermediate the FCC main column receiver and the gas plant associated with the FCC unit. The low H.sub.2 S lift gas does not increase SO.sub.x emissions from the regenerator as much as a recycled vapor from the FCC main column. As the lift gas is not purified in the gas plant it does not overload it.

摘要： A process is disclosed for upgrading reformate and/or light FCC gasoline by substantially reducing the amount of benzene in the gasoline product while simultaneously reducing the gasoline ASTM distillation End Point. The process comprises the fractionation of reformate to recover that fraction, C.sub.7 -C.sub.8 hydrocarbons, directly useful in gasoline without further conversion. A heavy bottom fraction comprising C.sub.9 + aromatic and non-aromatic hydrocarbons is recovered and a C.sub.6 fraction rich in benzene. The total C.sub.6 fraction and a portion of the C.sub.9 + fraction are converted by alkylation, transalkylation and cracking in contact with acidic metallosilicate catalyst particles to gasoline boiling range materials rich in alkylaromatics. Following debutanization or depentanization of the conversion product, the fraction containing unconverted benzene is recycled to the reformate fractionator.

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： 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.
