Latest Patents

Heikkila's latest patents reflect cutting-edge methodologies aimed at improving the efficiency and yield of xylose extraction. One notable patent describes a process for the separation of Ca- or Mg-sulfite spent liquor to yield crystalline xylose. This innovative approach involves a chromatographic separation utilizing a batch-type long resin bed column with a strong acid cation exchange resin. The process results in a xylose-rich fraction containing 50-70 wt. % xylose based on dry solids, along with a lignosulphonate-rich fraction. A further step in this process focuses on crystallizing xylose to enhance both yield and purity.

Another key patent by Heikkila is centered around the production of xylose and dissolving pulp from xylan-containing biomass, such as hardwood. This invention entails prehydrolysis of the biomass under specific conditions, followed by chromatographic fractionation, nanofiltration, or precipitation crystallization to obtain a high-purity xylose product. The dissolving pulp generated from this process holds significant potential for applications in the production of viscose.
