  • Patent number: 7029573
    Abstract: The invention relates to a composition and method for treating liquid hydrocarbons in order to remove acidic impurities, such as mercaptans, particularly mercaptans having a molecular weight of about C4 (C4H10S=90 g/mole) and higher, such as recombinant mercaptans.
    Type: Grant
    Filed: June 4, 2002
    Date of Patent: April 18, 2006
    Assignees: ExxonMobil Research and Engineering Company, Merichem Company

  • Patent number: 7014751
    Abstract: The invention relates to a method for treating and upgrading a hydrocarbon containing acidic species such as mercaptans, comprising: (a) contacting the hydrocarbon, in the essential absence of oxygen, with a first phase of a treatment composition containing water, dissolved alkali metal hydroxide, cobalt phthalocyanine sulfonate, and dissolved alkylphenylates and having at least two phases, (i) the first phase containing water, alkali metal alkylphenylate, dissolved alkali metal hydroxide, and dissolved sulfonated cobalt phthalocyanine, and (ii) the second phase containing water and dissolved alkali metal hydroxide; and then (b) separating an upgraded hydrocarbon.
    Type: Grant
    Filed: June 4, 2002
    Date of Patent: March 21, 2006
    Assignees: Exxonmobil Research and Engineering Co., Merichem Company

  • Patent number: 6960291
    Abstract: The invention relates to a method for desulfurizing naphtha boiling-range hydrocarbons such as cracked naphtha. More particularly, the invention relates to hydrotreating the naphtha under selective hydrotreating conditions, and then removing mercaptans from the hydrotreater effluent using a caustic extractant.
    Type: Grant
