Definitions
- the present invention relates to a method for extracting sugars and derivates thereof and the corresponding polysaccharides especially hemicelluloses from lignocellulosic biomass with hot water.
- the present innovation concerns a method to produce high concentration of high purity hemicellulose extract with minimal use of water.
- the extract is circulated through the biomass several times and as a result the concentration of the hemicelluloses in the water phase is increased.
- the circulating loop is vital in order for the non-hemicellulose material, such as lignin, to be adsorbed back to the biomass.
- the circulation also enables gentle extraction conditions regarding temperature, pressure and pH as the method does not require maximum extraction during the first extraction loop.
- Minimal oxidation and degradation of the hemicelluloses is achieved by removing virtually all of the air and especially oxygen gas from inside of the pores of the biomass during a impregnation step assisted by reduced pressure.
- the concentration of the extract is increased by using the same extract in several extractions of new and previously un-extracted biomass.
- Wood based biomass contains about 25% of hemicelluloses. Extraction of biomass is a very well known process and has traditionally been extracted with alkali. During this kind of treatment hemicelluloses are degraded and the fibrous material is decomposed.
- a resent method for extracting hemicelluloses from biomass involves continuous flow of hot water extraction.
- the problem with this method is, that it produces a very diluted extract containing up to 30% lignin impurities (WO 2009/122018 and Leppanen et al.: Pressurized hot water extraction of Norway spruce hemicelluloses using a flow-through system, Wood Sci Technol (2011) 45:223-236)
- a recent patent publication WO2007090926 describes a method for recovering hemicelluloses with higher concentration through steam hydrolysis.
- the drawback with this approach is that hydrolysis always involves deacetylation of the hemicelluloses which effectively lowers their water solubility and also degrades the polymers by lowering the molar mass.
- Chemical and food industry are interested in polysaccharides with high molar mass which the aforementioned method is unable to provide.
- Publication WO0061276 discloses a method for hydrolysis of hemicelluloses primarily into monomeric sugars which is a drawback especially if polymers are desired.
- the present invention is based on the finding that air and more specifically oxygen gas causes severe oxidation and degradation of sugars and polysaccharides at high temperatures. Reducing the air pressure inside of a reactor containing biomass, following the filling of the reactor with water effectively fills the capillaries of the biomass resulting in an almost completely oxygen free environment inside of the biomass.
- the present invention is further based on the finding that recirculation of the extract through the biomass purifies the extract from unwanted compounds such as lignin and other polyphenols.
- the presence of phenolic substances such as lignin in the extract lowers the capacity of microbes to digest polysaccharides and therefore the production of biofules becomes less economical.
- the method according to the invention allows a long time for the extract to be kept at high temperatures without significant oxidation and degradation of the molecules and polymers in the extract. This further allows the extract to be reused for extraction of un-extracted biomass which enables the consistency of the extract to be increased significantly without evaporation of the solvent.
- the energy value and the lignin content of the biomass increases.
- the fiber fraction properties become more suitable for the making of pellets and chipboards.
- the effect of extract circulation and impregnation under reduced pressure was investigated.
- the biomass was 200 grams (O.D.) of Scott spine chips ( Pinus Sylvestris ).
- the water to wood ration was 5:1.
- the extraction water was kept at 150° C. for two hours.
- the extract had circulated 10 times through the biomass.
- the pH of the extract was measured every half hour.
- a significant pH drop typically over one pH unit was recorded. This indicated that the formation of acids, especially through deacetylation of the biomass did not occur in the experiments with impregnation.
- the yield of the extractions is shown in FIG. 1 .
- the extracts were analyzed by gas chromatography for carbohydrates (Sundberg A, Sundberg K, Lillandt C, Holmbom B (1996) Determination of hemicelluloses and pectins in wood and pulp fibers by acid methanolysis and gas chromatography. Nord Pulp Pap Res JII(4):216-219) and lipophilic extractives (F. ⁇ rsa, B. Holmbom and J. Thornton, Wood Sci. Technol. 31 (1997) 279). Lignin was determined according to the method by Iiyama et al. (Iiyam, K.; Wallis, A. F A.
- FIG. 1 shows the extraction yield of six different extractions:
- Oxidation of the extracted components was prevented by keeping the extract in oxygen gas reduced environment. Extracting under minimized presence of oxygen gas produces a clear yellow and transparent extract. However, if the extract comes in contact with oxygen gas, it turns dark brown within minutes and the oxidization will continue even at room temperature. Extracts which were removed from the reactor into nitrogen saturated environment did not show signs of oxidization nor did the color of the extract change.
- FIG. 3 shows the consistency increase of the extract by reusing the extract.
