  • PROCESS FOR LIGNIN PURIFICATION AND ISOLATION
    Publication number: 20180298554
    Abstract: A method for removing inorganic salts from an alcoholic basic lignin solution, comprising the steps of adding an acid to said solution whereby an alcoholic lignin solution is formed, and separating a precipitate comprising an inorganic precipitate from said solution, and a method for separating lignin from an alcoholic basic lignin solution, comprising the steps of adding an acid to said solution whereby an alcoholic lignin solution is formed, separating a precipitate comprising an inorganic precipitate from said solution, removing ethanol from said solution, optionally adjusting the pH of the mixture obtained, and separating lignin from said mixture, and, a method for avoiding foaming during alcohol recovery from an alcoholic mixture comprising lignin, optionally after separation of an inorganic precipitate, which method is characterized in that a pH of 2 to 9 of the alcoholic mixture is adjusted during alcohol recovery
    Type: Application
