  • Patent number: 10597587
    Abstract: This invention provides a process for removing mercury, from a mercury-containing hydrocarbon fluid. More specifically, the invention relates to a process for the removal of mercury from a mercury-containing hydrocarbon fluid feed comprising the steps of: (i) contacting the mercury-containing hydrocarbon fluid feed with a metal perhalide having the following formula: [M]+[X]? wherein: [M]+ represents one or more metal cations wherein the metal has an atomic number greater than 36; an atomic radius of at least 50 pm and a 1st ionization energy of less than 750 kJmol?1; [X]? represents one or more perhalide anions; and (ii) obtaining a hydrocarbon fluid product having a reduced mercury content compared to mercury-containing hydrocarbon fluid feed.
    Type: Grant
    Filed: March 2, 2016
    Date of Patent: March 24, 2020
    Assignee: Petroliam Nasional Berhad (Petronas)

  • Patent number: 7914688
    Abstract: A method for breaking an emulsion of an ionic liquid which is a salt that is in the liquid state at a temperature below 1500 C, and an oil, comprising the steps of (a) irradiating the emulsion with microwave radiation; (b) separating the emulsion into an ionic liquid phase and an oil phase; and (c) recovering at least one of the phases.

  • Patent number: 6824599
    Abstract: Cellulose is dissolved in an ionic liquid without derivatization, and is regenerated in a range of structural forms without requiring the use of harmful or volatile organic solvents. Cellulose solubility and the solution properties can be controlled by the selection of the ionic liquid constituents, with small cations and halide or pseudohalide anions favoring solution.

  • Patent number: 6808557
    Abstract: A regenerated cellulose-encapsulated active substance and a method for encapsulating an active substance in a regenerated cellulose matrix are disclosed. The distribution of the active substance is preferably substantially homogeneous within the matrix of regenerated cellulose. The regenerated cellulose (i) has about the same molecular weight as the original cellulose from which it is prepared (ii) is substantially free of added substituent groups relative to the starting cellulose and is also substantially free of entrapped ionic liquid degradation products.
