    摘要: A process for recovering xylose from pentosan-containing raw materials includes the steps of hydrolyzing the raw material, feeding the hydrolyzed material to a chromatographic column comprising a strong anion-exchanger having a quaternary ammonium functional group fixed to a cross-linked polystyrene or acrylic resin matrix and eluting a xylose-rich fraction.

    摘要: A method as provided wherein betaine is separated eluted from beet molasses using a chromatographic simulated moving bed system having at least three chromatographic columns connected in series. The betaine is eluted during the same cycle as sucrose and rest molasses feeding and substantially simultaneous water feeding step, at least one water feeding step, a circulation step, and elution of sucrose, betaine and rest molasses fractions from selected columns.

    摘要: The invention relates to a method for the fractionation of molasses using a chromatographic simulated moving bed system in which the liquid flow is effected in a single direction in a system comprising at least two chromatographic partial packing material beds. In the method of the invention, the product or products are recovered during a multi-step sequence comprising the following phases: feeding phase of molasses, eluting phase and recycling phase. The liquid present in the partial packing material beds with their dry solids profile is recycled in the recycling phase in a loop comprising one, two or several partial packing material beds.

    摘要: The invention relates to a chromatographic separation column whose filling material space comprises in the vertical direction at least two zones between which no means that would hinder vertical flow exist and which are divided by means of substantially vertical walls into separate sections. These zones are so dimensioned that the upper edge of the walls in the uppermost zone is below the upper surface of the column filling material in the operating conditions of the column. The invention further relates to inner structures for such a column and to a chromatographic method for separating dissolved constituents by means of said separation column. In this method, a solution is fed alternately with an eluent uniformly across the upper surface of the filling material in the separation column, the solution is allowed to flow through the filling material bed, and the fractions containing the desired products are collected from the liquid flow passed through the filling material.

    摘要: The invention relates to a method for the fractionation of sulphite cooking liquor by a chromatographic simulated moving bed system in which the liquid flow is effected in a system comprising at least two chromatographic sectional packing material beds. In this method, at least one fraction enriched with monosaccharides and one fraction enriched with lignosulfonates are recovered during a multi-step sequence comprising the following phases: feeding phase of sulphite cooking liquor, eluting phase and recycling phase. The liquid present in the sectional packing material beds with its dry solids profile is recycled in the recycling phase in one or more loops comprising one or more sectional packing material beds.
