Definitions

  • the present invention relates to an improved process for pretreatment of wood raw material for saccharification. Also the invention relates to a system for carrying out of the process and product obtained by the process.
  • US2005069998 describes the pretreatment comprising stages of grinding the lignocellulosic biomass to a size of 15-30 mm, subjecting the product to steam explosion pretreatment at a temperature of 190-230 0 C for 1 to 10 minutes.
  • the steam explosion does not always break down lignin completely and some of the compounds produced can be inhibitory to the subsequent fermentation.
  • Biological pretreatment can involve applying lignin-solubilizing microorganisms.
  • the wood raw material may be subjected to pretreatment with the aim of producing substrates that can be more rapidly and efficiently hydrolyzed to yield mixtures of fermentable sugars; in turn the valuable chemical compounds can be obtained through fermentation from the sugars.
  • milling can greatly increase the susceptibility to enzymic depolymerization of cellulose.
  • two stage milling firstly a coarse milling to particles ranging in size from 1 mm to 2 mm and then ultraflne milling to particles 1-5 ⁇ m with mechanoactivation
  • two stage milling firstly a coarse milling to particles ranging in size from 1 mm to 2 mm and then ultraflne milling to particles 1-5 ⁇ m with mechanoactivation
  • Coniferous wood chips are milled in the ball mill (e.g. AS-2M, Novosibirsk) to size of 1 - 2 mm and are dried on hot air to humidity no more than 10%. The operating time of this process is 1 second. Then the obtained wood chips are extracted (e.g. using ultrasound-assisted extraction) with acetone or ethanol; the ratio of solvent to wood chips is in the range of from about 7:1 to about 10:1. The extracted wood chips are milled in the activation mill (AC-2C, Novosibirsk) to the size of l-5 ⁇ m. The total operating time is 3 seconds. The obtained product is mechanoactivated ultrafine powder with the particle size distribution given in the Table 1.
