Abstract
The invention discloses a method for preparing biogas and paper pulp from energy grass, belonging to the field of agricultural production. The method uses the energy grass as a raw material for high-efficiency production of biogas and paper pulp. According to the invention, the juice and residues of the energy grass are mechanically separated; the juice of the energy grass is subjected to anaerobic fermentation to prepare biogas; and the residues of the energy grass are used for production of paper pulp by using an ultrasonic-assisted biological enzyme method. The method provided by the invention realizes efficient and diversified utilization of the energy grass and provides a novel approach for comprehensive development and utilization of the energy grass.

Value does not maximize the use.
Paper pulp is the fibrous material obtained in Jing different processing methods with string as raw material.Can be according to processing method
It is divided into mechanical pulp, chemical pulp and chemimechanical pulp, it is the base stock of papermaking.Generally to the plant of pulping raw material
4 big class can be divided into：Stem fiber-like, bast fiber class, seed hair fiber class and lumber fibre class, stem fiber-like resource therein
Far from the needs for meeting growing pulp and paper industry.Paper, bast fiber class, seed hair fiber class needed for annual China
With lumber fibre class, all there is a problem of insufficient raw material, wherein especially with lumber fibre class as most important.Current China wood pulp
More than 40% needs from external import.
Biogas be organic substance under anaerobic, through a kind of mixed gas that the fermentation of microorganism is generated,
Its main component is methane and carbon dioxide, the gas such as also a small amount of nitrogen, hydrogen and hydrogen sulfide.Biogas is after purification highly concentrated
Degree methane, is also a kind of regenerative resource, and property is similar to natural gas.Biogas removes and directly burns for cooking, dries agricultural and sideline product
Product, heating, illumination and gas welding etc. are outer, can also make the fuel and production methyl alcohol, formalin, carbon tetrachloride of internal combustion engine etc.
Industrial chemicals.
The content of the invention
Object of the present invention is to provide a kind of method that utilization energy grass prepares biogas and paper pulp, is utilizing energy grass

The system of source grass.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of method that utilization energy grass prepares biogas and paper pulp, by raw material of energy grass biogas and paper pulp are produced, including as follows
Step：
1) fresh energy grass is first ground into 0.1 ~ 5cm, then grass juice factor and careless slag is separated into by mechanical expression；
2) energy grass grass juice factor prepares biogas：By step 1) in isolated grass juice factor carry out biogas fermentation, 30 ~ 55 DEG C of temperature,
Total dry content is 3 ~ 20wt.%, and an input and output material was then carried out every 3 ~ 10 days；
3) carelessly slag prepares paper pulp to the energy：Take step 1) in the isolated further removal of impurities of careless slag, crush after, in ultrasonic wave
Water, mixed enzyme are added in reactor, mixing enzyme concentration is 1 ~ 100mg/g, 10 ~ 100khz of ultrasonic frequency, first at 40 ~ 70 DEG C
At a temperature of react after 1 ~ 5h, be warming up to 90 ~ 120 DEG C and react 1 ~ 5h again, then through defibrination, washing, screen and dehydration obtains paper
Slurry.
Wherein, described energy grass be Pennisetum plant, Sorghum propinquum, sugar grass, giantreed, reed, class reed, spot thatch, that
In special grass, sudangrass, Caulis Miscanthis floriduli, reed, awns, Arundinella hirta (Thunb.) Tanaka, Plantula Neyraudiae Reynaudianae, silage corn, lemongrass, Spartina alterniflora, Value of Spartina Anglica, switchgrass
One or more.
The present invention remarkable advantage be：There is provided various utilization orientations of energy grass, made using the fermentation of energy grass juice factor
On the basis of standby biogas, while producing paper pulp, a kind of system of agriculturally comprehensive energy utilization grass is formed.The present invention can be efficient
Ground utilize energy grass, individually the efficiency of fermentation is higher than and is directly fermented using energy grass grass juice factor.Overall process no pollution of the present invention,
The product of any pollution environment will not be produced.The present invention has prominent novelty and practical value.
