Description
[technical field]
The invention belongs to bamboo timber resource and utilize the field, particularly the quick-fried refining of a kind of bamboo wood vapour prepares the method for ecomaterial and energy thereof.
[background technology]
The non-renewable fossil resource such as oil and natural gas has consisted of the foundation stone of world today's fuel and chemical industry.But since 21 century, because fossil fuel is non-renewable, and fossil fuel uses the environmental problems such as caused greenhouse effects, acid rain, dust pollution, from renewable plant resources particularly Wooden Biomass production chemical products with high added-value become the important development field of many countries and the focus of scientific research.The fundamental realities of the country of having a large population and a few land in view of China and the severe situation of worldwide energy crisis, the Developing Biomass resource conversion is utilized technology, and the exploitation bio-based energy, chemicals and material will provide strong guarantee to the resource security problem of China.
Bamboo is one of subfamily the most original in the grass, also is the diversified population of tool in the grass, the bamboo extensive growth in the Asia, Africa, Galle Latin American when, and enjoy high reputation in these areas.Bamboo is different from other equal plant with wooden stalk, compound branch, flourishing root system and the characteristics of seldom blooming, the bamboo stalk that can both grow several natural moulding every year, reach full growth and can come into operation.
China's bamboo resource is abundant, and plantation bamboo area ranks first in the world, and has 48 and belongs to, and kind more than 500 accounts for half of world's bamboo kind.Mao bamboon distributes the widest in China, the area of plantation mao bamboon reaches 2,700,000 hectares, accounts for 65% of bamboo grove area, and mao bamboon is a kind of perennial high megaphanerophyte, and it is distributed widely in middle subtropical zone.Bamboo Growth is fast, and output is high, and material is good, and purposes is wide, is the bamboo kind of China's economic worth maximum.The main component of mao bamboon comprises cellulose, hemicellulose and three kinds of compositions of lignin, these three kinds of components consist of the support frame of plant, wherein cellulose forms microfibre, consist of the mesh skeleton of plant cell wall, hemicellulose and lignin then are " adhesives " and " filler " that is filled between the cellulose.The summation of cellulose, hemicellulose and three kinds of components of lignin accounts for about 85% of gross weight (dry weight) in the mao bamboon, and wherein content of cellulose is generally 35-50%, and hemicellulose level is generally 15-25%, and the content of lignin is generally about 20%.Except the three major types component, also contain a small amount of protein, lipid, ash content, moisture, pectin, low molecular weight carbohydrate etc. in the bamboo wood.Wherein the content of ashes of bamboo is generally at 1-3%, and major part is silica in the ash content.
As a kind of green, renewable, degradable resource fiber, the exploitation prospect of bamboo fibre is wide, thereby has received more and more people's concern.At present, its mode of utilizing mainly contains weaving bamboo fibre, papermaking and viscose bamboo pulp, fibre-forming polymer based composites reinforcing material.But these utilize mode or the research of carrying out for Single Fiber element component utilization in the bamboo wood, and the application of other resources lacks enough attention, has caused the bamboo timber resource utilization rate not high, bamboo wood goods high in cost of production.
Mainly concentrate at present preparation and the development and use of bamboo fiber about the application of bamboo wood, Chinese invention patent CN1415790 for example, CN1406725, CN1375578, CN1390989, CN1083760, CN1621580A, CN1824851A etc. have all mentioned the employing chemical method, Physical or biological enzyme are produced bamboo fiber, but the method for mentioning in these patents all is the utilization of only carrying out for the good long fiber of bamboo wood performance, other a large amount of components go out of use or burned low value utilization, have not only caused a large amount of wastes of resource, and have caused serious environmental pollution.Therefore, be necessary the characteristics from bamboo material, comprehensive higher value application to bamboo timber resource carries out deep research, foundation is suitable for bamboo material refining technical system, both can realize the multicomponent complete utilization of bamboo wood, reduce the production cost of bamboo product, improve the added value of bamboo resource, can reduce the pollution that in the bamboo timber resource process, causes again.The inventor for this problem application patent of invention 200710177983.6, invented by the quick-fried technology of vapour and separated the method that component is fully used in the bamboo wood that makes in conjunction with long and short fiber, except obtaining purpose product bamboo fiber, simultaneously also coproduction the products such as xylo-oligosaccharide, bamboo pulp, ethanol, pure molten lignin, residual residue generating, the pollution and the one-component that have overcome in traditional bamboo fiber production process utilize problem.On this basis, for the development and use with the larger value of bamboo timber resource, the inventor has proposed a kind of new method that is prepared ecomaterial and energy thereof by the quick-fried refining of bamboo wood vapour.
[summary of the invention]
Main purpose of the present invention is to carry out environmental protection, high-valued comprehensive utilization for bamboo timber resource, the Development of Novel bamboo application technology, formation is suitable for bamboo material refining technical system, the high-efficiency cleaning of realizing each component in the bamboo resource separates, not only obtain the ecomaterials such as bamboo fiber, polyether polyol, Wood-plastic material, realize simultaneously the energy of bamboo timber resource.Thereby the maximum value utilization of each component in the realization bamboo timber resource improves the added value of bamboo wood, and reduces the pollution problem in the bamboo resource process.
