Description
Technical field
The present invention relates to a kind of preparation method of biological liquid energy resource, particularly relate to a kind of preparation method of timber biological liquid state energy source.
Background technology
The energy and grain are the base substance guarantees that the mankind depend on for existence.At present, worldwide energy consumption mainly is the conventional non-renewable energy based on coal, oil and natural gas, thereby its stock number is very limited.Energy dilemma and ecological crisis show especially day by day, and the energy become the bottleneck that restriction China economy develops rapidly, and crude oil import also becomes the major hidden danger of Chinese energy safety.Develop bioenergy reproducible, cleaning and have the important strategic meaning.Bioenergy is meant and passes through photosynthesis of plant, the energy that sun power is become organism and store, comprise the energy that each kind of plant, human and animal excreta and organic waste change into, as fuel wood, biogas, biofuel, alcohol fuel, agricultural crop straw, town and country organic waste, industrial and agricultural wastewater etc.Someone estimates that the stock on hand of bioenergy is 18,000 hundred million t, and wherein 90% is the forest reserves, but only has stalk and vegetable oil material can be applied to liquid biological energy source at present.Seeking as early as possible from forestry waste material (as bark, sawdust, brush wood), stalk and developing the new forms of energy that substitute oil is task of top priority, is pressing for of China energy strategy.Therefore, the development bioenergy will not only all be made huge contribution to China but also to human ecological environment.
The biological liquid energy resource production technology mainly comprises: chemical method, biological enzyme synthesis method, engineering microalgae method.
(1) the present biofuel of chemical method mainly is to utilize chemical method production, be that low-carbon alcohol such as animal and plant grease and methyl alcohol or ethanol are carried out esterification under acid or basic catalyst and high temperature (230 ℃～250 ℃), generate corresponding fatty acid methyl ester or ethyl ester, again through washing and be drying to obtain biofuel.Methyl alcohol and ethanol can be recycled in process of production, and production unit is identical with general device, can produce the byproduct-glycerine about 10% in the production process.The shortcoming of this kind method mainly is: technology is complicated, and alcohol must be excessive, and subsequent technique must have corresponding pure retrieving arrangement, and energy consumption is higher, and carboxylate is difficult to reclaim, and cost is higher, and the waste lye discharging is arranged in the production process.
(2) biological enzyme synthesis method biological enzyme synthesis method be with animal grease and low-carbon alcohol by lipase carry out transesterificationization send out should, prepare corresponding fatty acid methyl ester and ethyl ester.The enzyme process biodiesel synthesis has that mild condition, pure consumption are little, the advantage of non-pollution discharge.But subject matter has at present: low to methyl alcohol and alcoholic acid commentaries on classics esterification yield, and generally only be 40%～60%.Because lipase is effective to the esterification or the transesterificationization of long chain aliphatic alcohol at present, and low to short chain fatty alcohol (as methyl alcohol or ethanol) transformation efficiency, and short chain alcohol has certain toxicity to enzyme, the weak point in work-ing life of enzyme.By-product glycerin and shipwreck are in recovery.
(3) engineering microalgae method engineering microalgae method is a kind of brand-new production method of bio-diesel oil.This method is to utilize little algae (the little ring of engineering algae) to produce thing diesel oil next life, and it improves the output of biofuel by lipid content (bringing up to 60% from 5%) in the little algae of raising.Lipid content has been built up at 60% " engineering microalgae " by modern biotechnology in the renewable laboratory of American National (NREL).The superiority of utilizing " engineering microalgae " to produce diesel oil is: little algae throughput height, the biofuel sulfur-bearing not that can save agricultural resource (higher tens times than terrestrial plant per unit area yield grease), production as natural medium with seawater, do not produce obnoxious flavour during burning, free from environmental pollution.
At present, China's artificial fastgrowing trees cultivated area tool the first in the world, artificial forest wood is the important industrial fiber raw material forest seeds of China, is the desirable feedstock that is used for pulping and paper-making and wood-based plate.But in recent years, the China's timber resource is in short supply day by day, and its price is constantly soaring, causes the felling phase of all kinds of forests to shorten gradually, and particularly the felling phase of Chinese fir, pine tree, tamarack etc. contracted to 5～10 years.The extractives content of children's timber in age in pulping and paper-making, is not only wasted a large amount of SYNTHETIC OPTICAL WHITNER and auxiliary agent up to 12%, and strengthens the toxicity of waste water, causes the huge environmental pollution and the wasting of resources greatly, at a large amount of tackiness agent of Wood-based Panel Production waste.In order to make full use of resource, reduce environmental pollution, improve the wood utilization rate, the research of extract has been caused domestic and international investigator's great attention.Through reaching 10 years of researches, find the method for timber extract directional thermal decomposition, this kind method is expected to solve the major issue that relates to forestry, slurrying, papermaking, the energy and environment protection.
