  • Process for converting an alkyl tert-alkyl ether into an alkanol and an iso-alkane
    Patent number: 9067860
    Abstract: The invention relates to a process for converting an alkyl tert-alkyl ether into an alkanol and an iso-alkane wherein the alkyl tert-alkyl ether is contacted with a hydrocracking catalyst in the presence of hydrogen under hydrocracking process conditions.
    Type: Grant
    Filed: October 16, 2012
    Date of Patent: June 30, 2015
    Assignee: Shell Oil Company
    Inventors: Leslie Andrew Chewter, Hervé Henry, Pieter Oldenhove, Rajaram Ramesh, Jeroen Van Westrenen
  • Process for preparing an epoxide from an oxygenate
    Patent number: 8822709
    Abstract: The invention relates to an integrated process for preparing an epoxide from an oxygenate, wherein the oxygenate is converted into a lower olefin and the lower olefin is subsequently epoxidised, and wherein isobutane obtained after hydrogenation and subsequent normal/iso separation of C4 hydrocarbons obtained as by-product of the oxygenate conversion, is converted into a hydroperoxide that is used for the conversion of the lower olefin into the corresponding epoxide.
    Type: Grant
    Filed: October 16, 2012
    Date of Patent: September 2, 2014
    Assignee: Shell Oil Company
    Inventors: Leslie Andrew Chewter, Hervé Henry, Pieter Oldenhove, Rajaram Ramesh, Jeroen Van Westrenen
  • Process for preparing an epoxide from an oxygenate
    Patent number: 8822710
    Abstract: The invention relates to an integrated process for preparing an epoxide from an oxygenate, wherein the production of a lower olefin from the oxygenate and the subsequent epoxidation of the lower olefin is combined and wherein isobutene, a by-product of the lower olefin production, is converted into a hydroperoxide that is used for the conversion of the lower olefin into the corresponding epoxide.
    Type: Grant
    Filed: October 16, 2012
    Date of Patent: September 2, 2014
    Assignee: Shell Oil Company
    Inventors: Leslie Andrew Chewter, Hervé Henry, Pieter Oldenhove, Rajaram Ramesh, Jeroen Van Westrenen
  • Process for preparing organic hydroperoxides
    Patent number: 6011183
    Abstract: The invention relates to a process for preparing organic hydroperoxides by oxidation of a hydrocarbon feed with molecular oxygen at supercritical conditions, which process is carried out in the presence of a separate liquid water phase that is present in an amount of 0.5 to 20% weight on the weight of the feed as a water film on the inner walls of the reactor vessel.
    Type: Grant
    Filed: November 13, 1998
    Date of Patent: January 4, 2000
    Assignee: Shell Oil Company
