Abstract
The invention pertains to the field of hemp resource utilization. A great quantity of noil is generated in the preparation process of refined dry flax prepared after the degumming, carding, opening and scotching and other technologies of hemp raw materials. The invention relates to a method for adopting the long vegetable fiber-noil as a raw material for fermenting and producing alcohol, which provides a high-valued means for the utilization of the long vegetable fiber-noil. The noil of the invention refers to the noil generated in the production process of the long vegetable fiber with such degumming technologies as chemical degumming, biological degumming, steam exploded degumming, etc. Noil fermentation relates to two fermentation methods including synchronous diastatic fermentation and acid hydrolysis fermentation. The process opens a new way for the utilization of the long vegetable fiber-noil, provides a new direction for raw materials for alcohol production and supplies a new idea for the comprehensive utilization of hemp resources.
Description
Technical field
The invention belongs to hemp resource and utilize the field, particularly produce the alcoholic acid method as fermenting raw materials with the noil that produces in the bast-fibre treating processes.
Background technology
Fibre of flax for textile material belongs to Moraceae, annual herb, dioecy.China's crudefiber crop is modal hemp, flax, ramie, bluish dogbane, jute, sisal hemp and kendir seven major types, also have piemarker, gombo hemp, water fiber crops, piemarker, abaca, Pueraria lobota fiber crops etc. in addition, nearly 20 kinds of numb according to incompletely statistics kind, kind more than 6500 is the abundantest country of hemp resource in the world.Fibre of flax for textile material once was human important fiber, oil plant, food crop.Fiber crops mainly are based on fiber in the utilization of China, and traditional mode is rope making, makes gunnysack and knit burlap.Crudefiber crop stem phloem fiber is long tough and tensile, can be for weaving.After early 1980s, country started " gunny products heat ", indicate that the flax spinning industrial development enters the prosperous phase.Production, processing and the sale of flaxen fiber and goods thereof at present occupied critical role in Chinese national economy.
Flaxen fiber is that (bast fibre and leaf fibre) from the fiber that various fibre of flax for textile materials are obtained, comprises the phloem fiber and the monocotyledonous leaf fibres of annual or perennial herb dicotyledons cortex.The phloem fiber crop mainly contains ramie, jute, piemarker, hemp, flax, kendir and gombo hemp etc.Cell walls such as hemp, flax, kendir lignifying not wherein, the thickness length of fiber can be made textile raw material with cotton close, is made into various nice and cool grass lawns, grass cloth, also can with cotton, hair, silk or chemical fibre blending; Phloem fiber such as jute, gombo hemp cell wall lignifying, fiber is short, only suitable spinning rope and packaging gunnysack etc.Leaf fibres is more thick and stiff than phloem fiber, can only manufacture rope etc.Crudefiber crop also can be produced the raw material of chemical industry, medicine and papermaking.Flaxen fiber must be removed colloid when producing by the colloid bonding in flakes, makes fiber separation, claims to come unstuck.The fiber crops of coming unstuck after handling obtain flaxen fiber through technologies such as combing, shreddings again.
The main composition of bast-fibre raw material is: Mierocrystalline cellulose, hemicellulose, xylogen, pectin substance, the water solubles, also contain a spot of adipocere matter, ash grades in addition.Crudefiber crop raw fibre cellulose content is generally more than 50%, and hemicellulose level is generally about 15%, and xylogen is generally in 10%.Hemp is compared with ramie, flax, its gum level higher (〉 40%, unit is %):

Flaxen fiber is one of human textile fibres that utilizes the earliest.Flaxen fiber very easily produces a large amount of noils in spinning process, 1 ton of hemp line of bibliographical information production produces 1.2 tons of hemp noils approximately simultaneously.Flaxen fiber noil number is low, and the discrete length degree is big, and mean length is short, the short fiber content height.These noils can provide certain pulp raw material sources for papermaking, the numb viscose glue of production, for making full use of the crudefiber crop raw material resources, reduce the hemp spinning yarn cost, and improving the linen textile market competitiveness provides suitable wide prospect.
At present existingly much utilize bibliographical information, concentrate on mainly that crudefiber crop is come unstuck, the aspects such as utilization of flaxen fiber weaving, crudefiber crop medicinal ingredients study about hemp resource.Mainly concentrate on researchs such as jute viscose production, cotton ramie blended spinning for the noil utilization that produces in the fibrilia spinning process, and do not appear in the newspapers for bast-fibre noil ethanol fermentation aspect.
Summary of the invention
[purpose of the present invention] provides a kind of method of bast-fibre noil fermentative production of ethanol, makes that noil is high-valued to have overcome noil simultaneously and utilize single shortcoming, solved simultaneously that to produce in the ethanol grain source with grain raw material limited, an expensive difficult problem.Technical scheme of the present invention is as follows:
The method of [technical scheme] bast-fibre noil provided by the invention fermentative production of ethanol comprises the steps:
(1) get the raw materials ready: the flaxen fiber noil results from technological processs such as raw material comes unstuck, combing, shredding, the noil that produces in each technological process is mixed the back be used for follow-up fermenting alcohol as raw material; (described noil comprises the noil that produces in the degumming technologys production flaxen fiber processes such as chemical Degumming, biological degumming, vapour exploding degumming.)
(2) ethanol fermentation: comprise liquid glucose fermentation dual mode after simultaneous saccharification and fermentation and the noil acid hydrolysis;
1. simultaneous saccharification and fermentation: adopt simultaneous saccharification and fermentation to produce ethanol described flaxen fiber noil, add 3g noil (dry weight) in the 100ml triangular flask, add water according to solid-to-liquid ratio 1:5～1:12 then, regulating pH is 4.5～5.0; Inoculate 0.001～0.02g dry yeast, add the cellulase solution of 30～90FPU again, place 37 ℃ of water bath chaders, 150rpm oscillation and fermentation 72h obtains ethanol fermentation liquid.
2. acid hydrolysis fermentation: in the 100ml triangular flask, add 3g noil (dry weight), adding concentration then is that 65% sulfuric acid is hydrolyzed in 50 ℃ of water-baths according to solid-to-liquid ratio 1:15, hydrolysis 2h obtains liquid glucose, collect the liquid glucose inoculation 0.01g dry yeast 36-72h that in 30 ℃ of water-baths, ferments then, obtain ethanol fermentation liquid.
