Patent number: 9109265Abstract: 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.Type: GrantFiled: June 26, 2008Date of Patent: August 18, 2015Assignee: DUPONT NUTRITION BIOSCIENCES APSInventors: Heikki Heikkila, Jari Lewandowski

Patent number: 8816068Abstract: The invention relates to an improved process for the production of a sugar alcohol from the corresponding sugar through catalytic hydrogenation. Especially, the invention relates to a process for reducing the interference of sugar-derived aldonic acids in the hydrogenation process by adjusting the hydrogenation conditions so that the activity of the catalyst is maintained. In one embodiment of the invention, the process of the invention is carried out by adjusting the hydrogenation temperature by starting the hydrogenation at a lower temperature and then gradually rising the temperature to the final hydrogenation temperature. In another embodiment of the invention, the process of the invention is carried out by adding small-molecular monocarboxylic acids to the hydrogenation solution.Type: GrantFiled: April 26, 2007Date of Patent: August 26, 2014Assignees: Schott Solar AG, Dupont Nutrition Biosciences ApsInventors: Jyrki Kuusisto, Heikki Heikkilä, Matti Tylli, Martin Golde, Teppo Riihimäki
