Description
Technical field
The invention belongs to biomass energy technology fields, and in particular to a kind of non-enzyme-cellulose hydrolysis and saccharification technology.
Background technique
Lignocellulosic is the renewable biomass resources that nature is inexhaustible, nexhaustible.As petroleum, coal store up
The decline of amount and the growing interest of mankind's environmental pollution, the raw material of Chemical industry worldwide just gradually from fossil resource to
Biomass resource transformation, lignocellulosic are considered as the green bio resource of most possible substitution fossil energy.Wood fibre
Cellulosic biomass is by cellulose, hemicellulose and lignin) three kinds at being grouped as.Cellulose and hemicellulose are mainly carbohydrate height
Polymers, and lignin is using phenylpropyl alcohol alkane as the aromatic polymer of basic unit.Lignocellulose biomass passes through hydrolysis and saccharification, can
Be converted into monosaccharide substance, as platform, through chemistry, biocatalysis approach can be converted to biologically based fuels, fuel additive,
Fine chemicals etc.；The monosaccharide crystal obtained using crystallization purifying technology is more important the raw material of industry.It can be seen that wooden fibre
Biomass sugar derived from dimension element is the primary raw material and important platform material of biobased products, is reinforced to biomass sugar platform
Research and development will promote exploitation and the industrialization process of subsequent bio base product, and it is efficient to establish a new biomass resource
Using integrated industry, the sustainable development of economic society is realized.
But utilize the process of lignocellulose biomass production saccharide compound intermediate that there is sizable challenge.
Lignocellulosic hydrolysis and saccharification technique is concentrated mainly on " sour water solution " and " enzyme hydrolysis " two kinds of approach at present, and " enzyme hydrolysis " was saccharified
Although journey mild condition, since cellulase cost is excessively high, it is difficult to realize industrialized production.Fluid sulphuric acid, hydrochloric acid hydrolysis
Not only corrode equipment, but also post-processes and generate a large amount of waste water；There is contact of the catalyst with lignocellulosic again in solid acid hydrolysis
Problem, and catalyst is difficult to recycling and reusing.Cellulose due to stablize and complicated Supramolecular morphological structure make its be difficult to by
Hydrolyst is touched, and causes its reaction efficiency low.The accessibility of reinforcing fiber element is wanted, cellulose will be destroyed first
Macromolecular chain structure increases amorphous region and the contact area of cellulose.The reactivity of solid can be improved in mechanical activation, specially
Sharp CN201410787022 discloses a kind of method of mechanical activation collaboration metal salt degraded cellulose.This method by cellulose with
Metal salt mixture is put into ball mill, and ball milling activates 10~180 minutes under the conditions of 30~90 DEG C of degree, the results showed that, significantly
The degree of polymerization for reducing cellulose effectively increases the accessibility and reactivity of cellulose degradation product, but the system is only
Cellulose oligomer has been obtained, has failed to obtain monosaccharide.CN201510278766.0 discloses a kind of oxalic acid mixing and ball milling pretreatment
The method that corncob prepares xylose hydrolysis fluid.Corncob is ground screening first by the invention, is mixed into after screening with oxalic acid solution
Row ball milling pretreatment, mixture adds water and is ultrasonically treated after ball milling, hydrothermal pretreatment is then carried out in microwave reaction kettle, as a result
Xylose solution is obtained, cellulose does not hydrolyze.Document Chem.Sci., 2016,7,692-696 use planetary ball mill instrument by eucalyptus
Skin and two hours of catalyst mixing and ball milling, glucose yield is then hydrolyzed under 120ppm hydrochloric acid existence condition up to 80%,
But still have trace hydrochloric acid use and recycling sugar juice concentration it is very low.Patent CN201711010502.2 discloses one kind
Phosphorus pentoxide is catalyzed lignocellulosic hydrolysed ferment method, after lignocellulosic and phosphorus pentoxide mixing and ball milling two hours
Direct hydrolysis can get 80% glucose yield；But the technical process ball milling Ball-milling Time is too long to be caused to handle energy consumption mistake
It is high.
Summary of the invention
In view of the shortcomings of the prior art with deficiency, one of the objects of the present invention is to provide a kind of mechanical energy mutually to tie with thermal energy
Preprocessing lignocellulose is closed, saccharification processing energy consumption, investment operating cost is reduced, develops the hydrolysis sugar chemical industry of high-efficiency low energy consumption
Skill.The technology successfully improves the yield of lignocellulosic hydrolysed ferment and efficiency, treatment process efficiently separate out lignin components,
And the introducing without excessive metal ion, maximally utilizing for lignocellulosic material is realized, biobased products are effectively pushed
Realization industrialization process.
The present invention specifically provides a kind of non-enzyme-cellulose hydrolysis and saccharification technology, specifically includes the following steps: addition solid oxygen
Compound is mixed with cellulose-containing lignocellulosic material, after pre-processing in conjunction with mechanical energy and thermal energy to cellulosic biomass feedstock
Saccharification is hydrolyzed.It carries out respectively obtaining sugar juice and lignin components after reaction, realizes lignocellulosic
