    • A process for the separation of a xylose-containing, lignosulphonate-containing Ca-sulfite spent liquor is provided. The process comprises a first step of : (A) chromatographic separation of the Ca- or Mg-sulfite spent liquor using a single pass through a batch- type long resin bed chromatography column having a strong acid cation exchange resin as a separation medium. The ratio of the bed length: mean resin bead diameter of the column is 10,000- 40,000. This step yields •a first xylose-rich fraction having a xylose content 50- 70 wt. % based on dry solids and • a lignosulphonate-rich fraction. The process further comprises a step of : (B) crystallizing xylose from the first xylose rich fraction by using a crystallization method comprising (i) boiling crystallization; (ii) cooling crystallization or (iii) a combination of (i) and (ii) to obtain a first batch of crystalline xylose and a first xylose run-off. The process provides a simplification of existing methods, and at the same time allows advantages such as improved xylose yield and improved xylose purity.
    • 提供了一种用于分离含木糖的含木质素磺酸盐的亚硫酸钙废液的方法。 该方法包括以下步骤:(A)使用单次通过具有强酸性阳离子交换树脂作为分离介质的间歇型长树脂床色谱柱对Ca-或Mg-亚硫酸盐废液进行色谱分离。 床长的比例:柱的平均树脂珠粒直径为10,000-40,000。 该步骤产生具有木糖含量为50-70重量%的第一富含木糖的级分。 基于干固体和富含木素磺酸盐的级分。 该方法还包括以下步骤:(B)通过使用包含(i)沸腾结晶的结晶方法从第一富含木糖的级分结晶木糖; (ii)冷却结晶或(iii)(i)和(ii)的组合以获得第一批结晶木糖和第一木糖流出物。 该方法提供了现有方法的简化,并且同时可以获得诸如改善木糖产量和改善木糖纯度的优点。

    • The present invention relates to a fluid distributing device for distributing fluid into a column and to a fluid collecting device for collecting fluid from a column. The invention relates also to methods of using the devices of the present invention. The distributing device and/or the collecting device of the present invention can be used in fixed or fluidized bed reactors or columns, such as chromatographic separation columns, ion exchange columns, adsorption columns etc. A fluid distributing device comprises a) a first fluid conveying system; and b) a distributing plate, which comprises i) first means for fluid transfer for dividing the fluid flow coming from the delivering points into several partial fluid flows and for distributing the partial fluid flows into the column; and ii) first means for controlling of the partial fluid flows by differential pressure in the first means for fluid transfer.
