摘要： A low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by octane enhancing treatment in a fluidized bed catalytic process, in the presence of an aromatics-rich feedstream. The process converts the hydrodesulfurized intermediate and the aromatics-rich feedstream to a gasoline boiling range fraction of high octane number. The fluidized bed catalytic process is carried out over zeolite catalyst particles in a turbulent reactor bed at a temperature of about 600.degree. to 800.degree. F. (316.degree. to 427.degree. C.) and pressure of about 100 to 250 psig (790 to 825 kPa. The catalyst has an apparent particle density of about 0.9 to 1.6 g/cm.sup.3 and a size range of about 1 to 150 microns, and average catalyst particle size of about 20 to 100 microns containing about 10 to 25 weight percent of fine particles having a particle size less than 32 microns. The feed vapor is passed upwardly through the fluidized catalyst bed under turbulent flow conditions; turbulent fluidized bed conditions are maintained through the reactor bed between transition velocity and transport velocity at a superficial fluid velocity of about 0.3 to 2 meters per second. Treatment in the fluidized bed catalytic process restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha.

摘要： A process for multi-stage catalytic cracking is disclosed. A first stage cracks a first feed at atmospheric to 100 psig over a shape selective zeolite to convert from 10 to 90%, by volume, to lighter products rich in iso-compounds which may be used to make ethers. A second feed, which may include 700.degree. F.+ liquid from the selective cracking reaction, is cracked in a catalytic cracking (FCC) unit. Preferably all or some of the products from the shape selective cracking reactor are fractionated in the FCC main column.

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. Discharged 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.

摘要： A process and apparatus for fluidized bed catalyst regeneration. The regenerator contains a base fluidized bed, a bubbling dense bed above the base fluidized bed, and a dilute phase region above the bubbling dense bed. The bubbling dense bed has a larger cross sectional area than the base bed. Most, preferably all, the regeneration gas is added to the base fluidized bed. Higher superficial vapor velocities in the base fluidized bed, with conventional vapor velocities in the bubbling dense bed, allow more efficient regeneration in the base bed, without excessive catalyst entrainment into the dilute phase. Regenerated catalyst may be recycled from the bubbling dense bed or the dilute phase to the base fluidized bed, preferably via a cyclone dipleg.

摘要： A process 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 olefin upgrading technique and fixed-bed reactor system has been developed for increasing production of premium heavy hydrocarbons, such as distillate fuel, from lower olefinic feedstock. During recovery and recycle of intermediate range hydrocarbons products, a technique has been found for withdrawing a fraction rich in C.sub.5 -C.sub.9 gasoline range olefinic hydrocarbons from the oligomerization reactor effluent stream. By separating the reaction effluent in a multi-stage distillation system, fractionation feed can be separated into a heavier bottoms stream rich in C.sub.10 + hydrocarbons and a light hydrocarbon overhead, while withdrawing a liquid stream as an overflash fractionation stream rich in intermediate hydrocarbons. The overflash stream is combined to form a portion of the recycle stream to the reactor, thereby providing a more efficient and lower cost recovery process.
