Abstract
The invention provides a production method of biochemical lignin, and relates to the technical field of production of biochemical lignin. The production method specifically comprises the following steps: pre-treating collected forestry and agricultural residues; carrying out steam-explosion treatment, cleaning and solid-liquid separation to obtain a relatively pure solid matter; adding alkali to the solid matter; introducing steam; digesting for 2.5 to 3 hours at 80 to 100 DEG C to realize secondary solid-liquid separation; adding 10 to 100ppm of Ca(OH)2 to the separated liquid to flocculate and precipitate to obtain relatively pure supernate; filtering through a 20 microns filter to obtain pure liquid; and then carrying out membrane concentration, multi-effect evaporation and spray drying to obtain a pure biochemical lignin product. According to the production method of biochemical lignin, the raw materials adopted are the forestry and agricultural residues, so that the production cost is low, and the forestry and agricultural residues can be efficiently and comprehensively utilized; methane, furfural and solid biofuels can be produced while the biochemical lignin is produced, so that high economic value is brought; the oven-dry forestry and agricultural residues (wheat straw) per ton can be used for producing 0.15t biochemical lignin.
Description
Technical field:
The present invention relates to biochemical lignin (BCL) production technical field, be specifically related to a kind of biochemical lignin (BCL) production method.
Background technology:
Along with the understanding of the problems such as mankind's environmental pollution and crisis of resource deepens continuously, the character such as that natural polymer has is renewable, degradable comes into one's own day by day.The resource utilization of waste and the utilization of renewable resources, be the key subjects of modern economy and social development, is also the new demand that contemporary science and technology is proposed.At occurring in nature, the reserves of xylogen are only second to Mierocrystalline cellulose, and all regenerate with the speed of 50,000,000,000 tons every year.Pulp and paper industry will be isolated about 1.4 hundred million tons of Mierocrystalline celluloses every year from plant, obtain the xylogen byproduct of 5,000 ten thousand tons of left and right simultaneously, but up to now, surpass 95% xylogen still with " black liquor " directly enter rivers or concentrated after burn, seldom be utilized effectively.
For the agriculture and forestry organic waste materials of a large amount of generations in every year, still do not have at present efficient comprehensive Utilization Ways to be processed.
The develop rapidly of enriching reserves, xylogen science day by day exhausted, xylogen of fossil energy determines the sustainable developability of the economic benefit of xylogen.The xylogen cost is lower, xylogen and derivative thereof have several functions, can be used as dispersion agent, sorbent material/strippant, petroleum recovery auxiliary agent, asphalt emulsifier, xylogen is to the human kind sustainable development organic substance source that major contribution just is to provide stable, lasting the most, and its application prospect is very wide.So need a kind of from agriculture and forestry organic waste material or extract the method for xylogen from the byproduct of pulp and paper industry.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and the production method of a kind of biochemical lignin (BCL) is provided, and this production method can be extracted xylogen from agriculture and forestry organic waste material.
The present invention is a kind of by raw material is separated step by step, the scientific approach that layering is processed, isolate high purity, highly active biochemical lignin (BCL), and biochemical lignin (BCL) can partly substitute phenol, be applied in industrial production, thereby realize enterprise getting profit.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of biochemical lignin production method, its concrete steps are:
(1) the fiber biomass raw material of collection is carried out to pre-treatment, then send into the flash trapping stage device by e Foerderanlage, in the environment of 1.0MPa～2.0MPa after continuously cooking 1min～5min, cleaned again and solid-liquid separation, formed low dense liquid glucose and the comparatively pure solid substance of having removed most of hemicellulose and various vegetable polysaccharidess;
(2) add the alkali lye of its quality 4%～10% in the solid substance after flash trapping stage, and pass into steam, under the condition of 80-130 ℃ of temperature, after continuously cooking 0.5-2h, carry out the secondary solid-liquid separation, obtain biochemical lignin stoste and essential color fiber element pulp;
(3) separate the biochemical lignin stoste obtained, the Ca through adding 10-100ppm (OH) in step (2)
2flocculation, precipitation obtain comparatively pure biochemical lignin supernatant liquor, after crossing the filtration unit of 20um, suspended impurity is trapped, obtains liquid biochemical lignin products after membrane concentration, after the devices such as multiple-effect evaporation and spraying drying are processed, obtain solid-state biochemical lignin products again.
In described step (1), solid-liquid separation low dense liquid glucose is out sent in anaerobic fermentation system after the systems such as precipitation, pre-acidifying and adjusting are processed, in order to produce methane product.
The solid substance of separating in described step (2) is for the preparation of solid bio-fuel.
Described pre-treatment comprises the art breading such as cutting, removal of impurities.
Beneficial effect of the present invention is:
The raw material that the present invention uses is agriculture and forestry organic waste material, and the raw material resources amount is large, and distribution is wide, cost is low, makes the agriculture and forestry organic waste material resource obtain high-efficiency comprehensive utilization.By the present invention when producing the furfural product, can make the series product such as biochemical lignin (BCL), Mierocrystalline cellulose, biogas electric power and biomass molding fuel, the resource output capacity is high, environmental benefit is remarkable, when producing clean energy, produce large general industrial raw material product, can effectively with biomass resource, substitute fossil resource, promote the transition of energy substitution and the energy.After implementing the present invention, the agriculture and forestry organic waste material of over dry per ton (wheat straw) can be produced the biochemical lignin (BCL) of 0.15t, biochemical lignin (BCL) can part petroleum replacing based raw material---phenol, is applied to for product and industries such as sheet material tackiness agent, foaming thermal-insulatings.
The accompanying drawing explanation:
Fig. 1 is process flow sheet of the present invention.
