Definitions

  • the extracted lignocellulosic materials are added with water to a second extraction stage, along with alkaline sodium sulfide (ASS) and sodium borohydride (SBH), and treated at an elevated temperature of between 120° C. and 180 C.
  • the double extracted lignocellulosic materials are added with water to a digester, along with sodium hydroxide and sodium sulfide to produce pulp.
  • the black liquor released from the digester comprises, for example, dissolved lignin, sodium sulfide, sodium borohydride, sodium hydroxide, sodium sulfide, other chemicals, and cellulose and hemicellulose degradation products.
  • Paper products prepared from Processes 3 - 5 were compared to control paper products.
  • PFI mill refining response, apparent density, breaking length, burst index, tear index, and folding endurance of pulp prepared by Processes 3 - 5 were compared to pulp prepared from a pure Kraft process and pulp prepared from a Kraft process preceded by a water extraction.
  • Graphs 18 - 28 illustrate these comparisons and show that paper products prepared by Processes 3 - 5 are comparable to paper products prepared by pure Kraft processes and by Kraft processes preceded by a water extraction.
  • Paper products from representative versions of each of Processes 3 - 5 were compared with the two controls: Process 3 for a 20% PS; Process 4 for a 15% PS+0.5% SBH; and Process 5 for 15% PS and then 6% PS+0.5% SBH.
  • a treatment stage wherein the treatment stage is selected from the group consisting of a second extraction process, an agent impregnation process, and a first pretreatment process;
  • the lignocellulosic materials can be treated with Kraft white liquor containing polysulfide and reducing agent with or without anthraquinone and its derivatives, and the second pretreatment process can be maintained at a temperature below 150° C. for at least 30 minutes.
