Description
(1), affiliated field
What the present invention relates to is a kind of method of utilizing of agricultural crop straw, specifically a kind of method of extracting the effective ingredient in the agricultural crop straw.
(2), background technology
The main chemical of agricultural crop straw is Mierocrystalline cellulose, pentosan, xylogen etc.The content of each Chemical Composition is different in the different agricultural crop straws.But the total amount of above-mentioned three kinds of materials remains on about 70% substantially.Along with science and technology development, the method for utilizing of multiple kinds of crops stalk has appearred.Wherein utilizing agricultural crop straw to extract wood sugar and Xylitol is exactly wherein a kind of.But the existing method of utilizing agricultural crop straw to extract wood sugar and Xylitol exists multiple weak point, be mainly reflected in: 1, not only cellulose, pentosan, xylogen etc. have the composition that utilize to be worth in the agricultural crop straw, also contain compositions such as protein, starch, fat, pectin, pigment, metal ion, inorganic salt, tannin and chemical fertilizer and agricultural chemicals, the existing method of utilizing, these compositions can not be removed, the quality of the product that obtains is low, production cost is high.2, owing to compositions such as starch can not be removed, starch at high temperature can change into glucose and influence the quality of wood sugar, so what existent method adopted all is the low temperature hydrolysis method, not only hydrolysis effect is poor, speed is slow, and the acid solution that must add high density just can be hydrolyzed, bring the handling problem of acid solution in the hydrolyzed solution so again, after hydrolysis, must carry out neutralizing treatment thus, increased cost.3, hydrolysis can not be carried out continuously, and efficient is low.And adopt the activated carbon decolorizing cost high.
(3), summary of the invention
The object of the present invention is to provide a kind of quality of wood sugar and xylitol products that can make to improve greatly, the method for from agricultural crop straw, extracting wood sugar and Xylitol that production cost reduces greatly.The object of the present invention is achieved like this: be raw material with the agricultural crop straw; With raw material pulverizing, add raw material weight 4-6 water doubly, under 125-135 ℃ of temperature boiling 1.5-2.5 hour; With 75-85 ℃ hot wash 3-5 time; Adding raw material weight 2-4 concentration doubly is the acid solution of 0.65-0.75%, in the processing that is hydrolyzed of 105-115 ℃ of temperature, reaches 8-10% to xylose concentration; Filter; Adopt resin to decolour; Adopt ion exchange resin to carry out ion exchange treatment; Carrying out evaporation concentration under at 0.09Mpa, smaller or equal to 75 ℃ condition handles; Be cooled to 60 ℃, spraying drying obtains xylose product.Method of the present invention can also comprise like this some technical characterictics: 1, after hydrolysis to wherein feeding high pressure hydrogen.Make wood sugar change into Xylitol.2, described agricultural crop straw is a corn cob.3, described hydrolysis treatment is that the continuous hydrolysis that carries out in 3-4 the placed in-line hydrolytic decomposition pot is handled, raw material after wash the river flowing from Guizhou Province through Hunan into Dongting Lake joins elementary hydrolytic decomposition pot earlier and once is being transported to the next stage hydrolytic decomposition pot, hydrolyzed solution is from final stage hydrolytic decomposition pot upwards one-stage hydrolysis jar revolution successively, and the hydrolyzed solution of drawing from elementary hydrolytic decomposition pot enters the filtration operation.4, described filtration is that vacuum suction filter combines with flame filter press.The total content of Mierocrystalline cellulose, pentosan, xylogen etc. is about 70% in the various agricultural crop straws, but the content of various concrete compositions is distinguished to some extent in the different agricultural crop straws.Though Gu the multiple kinds of crops stalk all can be used as the raw material that extracts wood sugar and Xylitol, the resulting effect of different agricultural crop straws can be different.The content of pentosan can reach a new horizontal 5-40% in the corn cob, and in the rice husk, straw the content of pentosan only 22% and 19%, so the present invention is with the preferred feedstock of corn cob as extraction wood sugar and Xylitol.High-temperature water boiling of the present invention and high temperature washing step, the protein, starch, fat, pectin, pigment, metal ion, inorganic salt, tannin and the chemical fertilizer that are contained in the agricultural crop straw and the residue of agricultural chemicals etc. can be removed extracting the useless or disadvantageous material of wood sugar and Xylitol, particularly removed starch wherein, avoided that starch changes into glucose in the process of separating, be convenient to adopt the hydrolysis process of high temperature, low acid concentration; Adopted high temperature, low acidity continuous hydrolysis technology, the percent hydrolysis of pentosan improved greatly, reduced the loss of wood sugar, improved the extraction yield of wood sugar, particularly omitted after the hydrolysis in and operation, simplified technology, reduced cost, reduced environmental pollution; The present invention adopts resin decolorization, resin ion-exchange, reduced in other extracting method in and operation; Adopted spray-dired drying means, taken away moisture content with cleaning exsiccant hot blast, obtained the tiny xylose product of particle, crystallization velocity is fast, can save crystallization time more than 30 hours.The present invention improves quality product by optimized choice, allotment to extraction process greatly, and the wood sugar purity that obtains can reach more than 90%, and does not wherein contain glucose, and the wood sugar standard can meet international standards.The wood sugar that can adopt high-pressure hydrogenation process hydrolysis can be obtained after the hydrolysis changes into Xylitol.The wood sugar yield of method of the present invention can be up to one-tenth more than 25%, and 4 tons of corn cobs can produce wood sugar more than 1 ton.Production cost is low, than the production cost decline 2/3 of other production method.The construction investment that method of the present invention can make simultaneously reduces greatly.
