摘要： An improved fluid-bed reaction process and apparatus are disclosed in which feedstock is preheated and may be at least partially converted by contacting the feedstock with spent catalyst in a preheat zone. Additional benefits include a reduction in catalyst poisons and coke production in the reaction zone. By contacting the fresh feed with hot spent catalyst, at least a portion of the coke which would otherwise form in the reactor is deposited on the spent catalyst. Temporary catalyst poisons are also sorbed onto the spent catalyst. The spent catalyst is then withdrawn from the preheat zone, stripped of entrained hydrocarbon and regenerated.

摘要： A semi-continuous multi-stage catalytic technique for converting lower olefinic feedstock to heavier liquid hydrocarbon product. The invention provides methods and means for: (a) contacting alkene-rich feedstock at high space velocity elevated temperature in a continuous primary stage reaction zone with shape selective medium pore zeolite oligomerization catalyst particles to convert at least a portion of the lower olefinic components to intermediate olefinic hydrocarbons, said primary stage catalyst having an average acid cracking activity of about 0.1 to 20; (b) cooling primary stage oligomerization reaction effluent from the primary stage reaction zone to condense at least a portion of the intermediate hydrocarbons, separating the cooled and partially condensed primary reactor effluent stream in a primary phase separation zone into a light gas phase stream comprising light hydrocarbons and a condensed liquid intermediate hydrocarbon stream; and (c) contacting at least an intermediate effluent portion from the primary stage with shape selective medium pore zeolite oligomerization catalyst in a high pressure fixed bed secondary stage distillate mode catalytic reactor system at elevated temperature and high pressure to provide a heavier hydrocarbon effluent stream comprising distillate hydrocarbons, said secondary stage catalyst having an acid cracking activity of at least 5. A simplified second stage reactor system permits the use of one or more fixed bed reactors to be operated intermittently.

摘要： A process and apparatus for low cracking or recracking of liquid hydrocarbons with FCC catalyst containing 0.2 to 1.5 wt % coke is disclosed. FCC naphtha, or a thermally or hydrocracked naphtha, contacts spent FCC catalyst in a naphtha recracking reactor for limited conversion to lighter products and an increase in octane number. Spent catalyst from the recracking reactor can be recycled to the FCC reactor without stripping or regeneration. Naphtha recracking products are preferably cooled, then used as an absorbent to recover gasoline boiling range products from the FCC main column overhead vapor. Use of spent catalyst and controlled conversion conditions minimizes overcracking of the light liquid and minimizes formation of heavy ends.

摘要： A process is disclosed for the production of tertiary alkyl ethers wherein linear olefins, particularly n-butene, are isomerized in the vapor phase at high temperature in contact with shape selective metallosilicate catalyst to produce iso-olefin vapor, particularly isobutene. The vaporous iso-butene is then etherified with alkanol to provide alkyl tert-alkyl ether such as MTBE. Unreacted iso-olefin and/or linear olefin and product ether are separated by fractionation and unreacted olefin components recycled. Fractionation of the vapor phase etherification product is carried out by using the fresh liquid linear olefin feedstream as a reflux stream to the fractionator.

摘要： A multistage process for etherifying C.sub.4.sup.+ aliphatic hydrocarbon feedstock containing isoalkane including the step of contacting the hydrocarbon feedstock with dehydrogenation catalyst at elevated temperature under dehydrogenation reaction conditions to obtain C.sub.4.sup.+ isoalkene and hydrogen, and separating dehydrogenation effluent to obtain an olefinic stream rich in isoalkene and a hydrogen stream.The olefinic stream and aliphatic alcohol are contacted in an esterification stage under partial etherification conditions with a regenerable inorganic metal oxide acid solid catalyst to convert a major amount of the isoalkene to C.sub.5.sup.+ tertiary-alkyl ether. In the preferred embodiment, effluent recovered from the first stage containing ether product, unreacted alcohol and unreacted olefin including isoalkene is charged to a second stage catalytic distillation column containing solid acid resin etherification catalyst in a plurality of fixed bed catalysis-distillation zones to complete substantially full etherification of isoalkene.At least a portion of recovered hydrogen is employed for contacting the regenerable etherification catalyst to remove feedstock impurity and coke and to restore acid activity. In the manufacture of MTBE, the alcohol consists essentially of methanol and the C4+ feedstock consists predominantly of C.sub.4 hydrocarbons containing isobutane. The first etherification stage catalyst may comprise medium pore zeolite and the second stage catalyst may comprise polymeric sulfonic acid resin.

摘要： Methanol or other alcohol is converted to high octane gasoline components in an integrated apparatus wherein crude aqueous alcohol feedstock is extracted with a liquid extractant stream containing C.sub.4 + iso-olefin and reacted to form tertiary-alkyl ethers, such as MTBE. The aqueous raffinate is converted to olefinic hydrocarbons in a MTO catalytic reactor. Propene from the MTO reaction is reacted with water to produce di-isopropyl ether, which may be blended with MTBE and C.sub.6 +MTO hydrocarbons to produce high octane gasoline. Isobutylene and isoamylenes from the MTO reaction can be recovered and recycled as a liquid extractant stream.
