Description
Technical field
The present invention relates to a kind of preparation methods of sand sagebrush (Artemisia filifolia) charcoal, belong to charcoal technical field.
Background technique
For a long time, sandy soil because nutrient it is barren, easily flow, the factors such as water retention property difference seriously restrict sandy soil application with
The development of husky raw crop.And charcoal be high nutrient content made of biomass carbonizes under vacuum or hypoxia condition, it is loose more
The rich carbon product in hole is the good material for carrying out soil quality promotion.
Contain various nutrient elements in charcoal, but essential element is C, H, O etc., wherein C content highest, it is general reachable
38% ~ 76%, in addition to this, charcoal also contains that there are many nutrients needed for plant growth, such as N, P, K, Ca, Mg.Biology
Charcoal is the product that biomass pyrolytic obtains, and inner element is concentrated and is enriched in pyrolytic process, is caused most of in charcoal
Constituent content is significantly higher than biomass, and especially C element performance is the most prominent.
According to the production technology of charcoal and turning property of physics and chemistry, the application approach of charcoal can be divided into agricultural, the energy, supported
Grow 5 aspects such as industry and environmental protection and byproduct application.Agriculture aspect, refers mainly to that charcoal, fertilizer are administered alone in the soil
Material or the functional biological carbon composite that application is mixed with other materials.Not only have the function of improveing soil, increase soil fertility,
But also have the function of increasing remittance emission reduction, improve plant growth environment and improving product quality.It is applied primarily to farmland, forest land
The lawn and.In terms of the energy, charcoal has good burning performance, and has the characteristics that calorific value is high, cleans, is pollution-free.It is produced after plastotype
Carbonized biomass coal bulk density with higher and intensity, not only high combustion efficiency, clean and environmental protection, and convenient transportation and storage
Hiding, therefore the non-renewable energy resources such as coal and combustion gas can be replaced, it can be used for the warm power generation of confession etc. in rural area, city.Cultivation aspect,
Charcoal, which can be blended in fowl poultry kind feed, increases culture efficiency.In addition, charcoal to be thrown into the water surface of aquaculture, not only
It can purify water, bait can also be precipitated and play antisepsis.In terms of environment, charcoal is answered because having adsorption capacity
Adsorb, purify water for heavy metal adsorption, pernicious gas etc..In terms of byproduct, to biomass carbonated obtained by-product
Object（Gaseous mixture and bio oil）Further processing can produce H2And other chemicals, it is alleviated to a certain extent to fossil base
The dependence of the energy and raw material reduces the carbon emission of the fossil base energy and raw material.It also can promote abandoned biomass resource simultaneously
Effective use and management, beautify the environment.
Sand sagebrush (Artemisia filifolia) long-term lacking stump and is cradled due at present more by as plant of defending and controlling sand, and makes sand sagebrush (Artemisia filifolia) increment
It greatly reduces, and the death of large area occurs in many areas.Sand sagebrush (Artemisia filifolia) stump can be obviously promoted its growth, and stump can make plant height
It increases sharply with the evil power of sprouting of Cong Jing and shoot, suitably cradles the growth that also can promote sand sagebrush (Artemisia filifolia), enhance its viability.
Stump or the sand sagebrush (Artemisia filifolia) after cradling transform into charcoal and seal up for safekeeping in fixed or semifixed sand ground, on the one hand can use charcoal
Stability（It can be stabilized more than one thousand years in the soil under certain conditions）It realizes the purpose that carbon converges, is mitigation of global climate
Variation contributes；On the other hand it using the characteristics such as the porosity of charcoal, hydrophily, adsorptivity, nutrient be abundant, realizes
Improve the effect of sand ground environment.Summary of the invention
The technical problems to be solved by the invention：For the problem that existing sand ground nutrient is barren and water retention property is poor, one is provided
The preparation method of kind sand sagebrush (Artemisia filifolia) charcoal.

In formula furnace, under the nitrogen protection of 50ml/min, 600~800 DEG C are warming up to, constant temperature activates 1~2h, obtains activation sand sagebrush (Artemisia filifolia)；
（4）It takes activation sand sagebrush (Artemisia filifolia) to be placed in 12~14h in 0.1mol/L hydrochloric acid solution, filters, rinse filter with 100g60 DEG C of deionized water
Slag 5~8 times, sand sagebrush (Artemisia filifolia) active carbon is obtained after drying；
（5）Hydrofining, caprolactone, glycidyl methacrylate and benzyl alcohol are taken, reacts 48h under the conditions of 50 DEG C, is obtained anti-
Answer liquid A；
（6）0.01mol/L hydrochloric acid solution is added in reaction solution A, is stirring evenly and then adding into n-hexane and generates precipitating, precipitating is true
Sky is dry for 24 hours, obtains degradable crosslinker；
（7）It takes sheep dung ball, deionized water, degradable crosslinker and sand sagebrush (Artemisia filifolia) active carbon to be uniformly mixed, stirs 30min, after drying
To sand sagebrush (Artemisia filifolia) charcoal.
Step（2）The heating rate is 20 DEG C/min.
Step（3）The mass ratio of the pretreatment sand sagebrush (Artemisia filifolia) and potassium hydroxide is 6：5.
Step（3）The heating rate is 10 DEG C/min.
