  • Production of middle distillate range hydrocarbons by light olefin upgrading
    Patent number: 5073351
    Abstract: An oligomerization system is provided for upgrading lower olefins to distillate hydrocarbons, especially useful as high quality jet or diesel fuels. The olefinic feedstock is reacted over a shape selective acid zeolite, such as ZSM-5, to oligomerize feedstock olefins and further convert recycled hydrocarbons. Reactor effluent is fractionated to recover a light-middle distillate range product stream and to obtain gasoline and heavy hydrocarbon streams for recycle.
    Type: Grant
    Filed: March 13, 1989
    Date of Patent: December 17, 1991
    Assignee: Mobil Oil Corporation
    Inventors: James H. Beech, Jr., Hartley Owen, Michael P. Ramage, Samuel A. Tabak
  • Production of middle distillate range hydrocarbons by light olefin upgrading
    Patent number: 4849186
    Abstract: An oligomerization system is provided for upgrading lower olefins to distillate hydrocarbons, especially useful as high quality jet or diesel fuels. Thye olefinic feedstock is reacted over a shape selective acid zeolite, such as ZSM-5, to oligomerize feedstock olefins and further convert recycled hydrocarbons. Reactor effluent is fractionated to recover a light-middle distillate range product stream and to obtain gasoline and heavy hydrocarbon streams for recycle.
    Type: Grant

    Date of Patent: July 18, 1989
    Assignee: Mobil Oil Corporation
    Inventors: James H. Beech, Jr., Hartley Owen, Michael P. Ramage, Samuel A. Tabak
  • Split-feed naphtha reforming process
    Patent number: 4839024
    Abstract: A naphtha feedstock is reformed by splitting the feedstock into a first C.sub.6 or lower fraction and a C.sub.7 and higher fraction, and passing the C.sub.6 and lower fraction to a reactor and combining the effluent from the first reactor with the C.sub.7 and higher fraction and passing the mixture to a second reactor. The reformate produced has an octane rating at least equivalent to that produced by conventional processes, but has a lowered benzene content.

  • Increased gasoline octane in FCC reactor
    Patent number: 4459203
    Abstract: The operation of FCC apparatus is improved by decreasing oil partial pressure in the FCC reactor riser by about 10 psia, as compared to the normal oil partial pressure in the riser, thereby increasing octane rating of the gasoline produced in the FCC unit. The oil partial pressure may be reduced by injecting a suitable amount of an inert diluent into the riser, or by decreasing throughput of the FCC reactor.

  • FCC Reactor with a downflow reactor riser
    Patent number: 4385985
    Abstract: A fluid catalytic cracking (FCC) process and apparatus using a riser and a reactor for cracking of petroleum feeds in the presence of a catalyst and a regenerator for regenerating the spent catalyst are improved by providing a downflow riser. The downflow riser assures uniform distribution of the catalyst throughout the feed, decreases contact time of the catalyst with the feed and decreases the amount of coke made in the process.
