Biodiesel Technology
Building of experiment of courtyard of province forest division 105 rooms, oil plants of a bag of plant is entered inferior in critical and extractive device. After about one hour, open the switch valve of device bottom, crystal vegetable oil flows. This is the first pace of refine biology derv.
Province forest division has to produce per year experiment of 3000 tons the sex intermediate to produce a workshop inside courtyard forestry centre. Inside this workshop, it is grease of fructification of ground channel oil or smooth Pi Shu, white wingceltis no matter, carry not complex refine process, can be made finally biology derv.
The sources of energy of bureau of forestry of director of research center of technology of project of derv of biology of one of author of key laboratory of Hunan Province of breeding of clone of dean of courtyard of province forest division, forest, province, country does core expert the honor of …… Li Changzhu a lot of. This is born in on century the person of Hunan path county at the beginning of 60 time, begin to devote into after graduation mix at derv of plant of the sources of energy, biology research of economic forest breeding, nowadays already is industry of energy of domestic live thing is absolutely get military thing.
Current, the project of promotion of forestry science and technology inside forestry centre of courtyard of province forest division sets an example inside base, built to produce per year 3000 tons intermediate sex experiment to produce a workshop. Inside this workshop, it is grease of fructification of ground channel oil or smooth Pi Shu, white wingceltis no matter, can be made finally biology derv.
The experiment completes plant extraction process one hour
Inside the 105 rooms of building of experiment of courtyard of province forest division, xiao Zhigong of researcher of courtyard of Hunan Province Lin Ke, doctor mentions adroitly oil plants of a bag of plant, enter inferior in critical and extractive device. After about one hour, open the switch valve of device bottom, crystal vegetable oil flows.
Before the experiment, these oil plants passed pretreatment: Rind, tool set. Xiao Zhigong says, this is to raise the be heated area of oil plants, raise oil yield. The basis is hanged in the ” of “ operating rules on the wall, plant oily extraction shares 14 measure. In spot experiment, xiao Zhigong generalizes his for 3 parts: Above all, pour oil plants into extractive boiler, take vacuum position with vavuum pump; Then, pump of loop of the hot water that start, heat through boiler circulation extractive boiler, join extractive agent to have mix. In this one process, the temperature that does not need with the seed and time have difference a bit. Ordinary control heats temperature comes for 45 ¡æ 50 ¡æ , when using, be probably 45 to 50 minutes; Finally, stop agitate, put out pump of hot water loop. With extractive agent compound makings fluid flows into detached axe, depart reclaims extractive agent, valve is opened after it is normal to fall in detached axe pressure, the oil that has made can be poured out of from here directly. And reclaiming extractive agent can be used circularly. #p#·ÖÒ³±êÌâ#e#
This suit buy is mixed by courtyard of province forest division cooperative cartel research and development, the loop that can realize resource not only is used, still have raw material the advantage of wide comfortable sex. Besides smooth Pi Shu, the fructification of floral of oil plants the sources of energy such as castor-oil plant, tung oil tree, white wingceltis, Shan Cangzi can pass extraction of this suit buy oily.
In fact, the refine process of biology derv is not complex, altogether cent is two paces: The first pace passes plant seed picked, drying, compress, fine, make vegetable oil; The 2nd pace is in reaction device, vegetable oil and methanol, activator union undertakes changing, extraction makes the product at the beginning of biology derv, repass distill, billabong makes plant bitumen and biology diesel oil. This one phase gives birth to the biology diesel oil that produce, use at the equipment such as boiler normally, but if want to put in in car market, still need to join tripartite auxiliary to be mixed further make up BD5 or BD20, make product burning behavior the biggest change. “BD5 adds diesel oil of 5 litres of biology in 100 litres of derv namely, BD20 adds 20 litres namely. Zhang Aihua of ” assistant researcher says, at present our country already tried to execute fuel of biology of BD5, BD10 in Hainan.
Raw material development goes more to be not edible wood this fuel
Inside forestry center of test of courtyard of province forest division, the smooth Pi Shu with a low platoon grows trimly on hill slope, hang on branch full the fructification of shape of grain of tuft bunch white. Fructification of smooth skin tree is one of important raw material of refine biology derv.
Although “ edible grease can regard biology derv as raw material, but China is population big country, do not dispute the basic national policy that grain is our country with the person. Smooth Pi Shu is in aptly quite the Yangtse River with south grow, in addition smooth Pi Shuke cultivate in order to be on barrener limit sex land and do not take up farmland. Zhang Aihua of ” assistant researcher says.
2007, li Changzhu is the first established resource of seed of “ smooth Pi Shu and research of clone seed selection and demonstrative ” project, obtained Hunan Province science and technology to progress 2009 second-class award. By them the oil content of smooth skin tree of seed selection rose 10% , yield rises 30% .
70% what the raw material cost of biology derv holds the whole cost that make oil. Li Changzhu says: “ raw material is bottleneck, everybody pays close attention to now more it is to change, the market. ” because this, what Li Changzhu group does now is to develop more blame edible wood this fuel, besides smooth Pi Shu, 2010, their group new developed new energy resources to cultivate kind of white wingceltis. Zhang Aihua says, white wingceltis oil content is high, yield is high, short change easy picked. #p#·ÖÒ³±êÌâ#e#
Current, the project of promotion of forestry science and technology inside forestry centre of courtyard of province forest division sets an example inside base, built to produce per year 3000 tons intermediate sex experiment to produce a workshop. Inside this workshop, it is grease of fructification of ground channel oil or smooth Pi Shu, white wingceltis no matter, can be made finally biology derv. A few kinds of different raw material are final producible piece same a standard product, this has a professional name in academia, call “ raw material ” of wide comfortable sex. This is Li Changzhu’s original creation, also be the original creation of Hunan.
Another contribution of Li Changzhu is, will be in the floral of the sources of energy that breaks up condition all the time choice, breeding, help advance somebody’s career and machine union to rise, make biology fuel oily scientific research and technology are changed make an organic whole, started the whole industry chain from former expect market, preliminary realized industrialization development. Seed selection of new breed of high yield of oil plants of industry of farmland of this “ blame and high cost are changed use ” technology to obtain judge ” of award of progress of “ country technology is second-class 2014 award.
Use the gas station on water and enterprise boiler
Besides the honor of scientific research respect, xiao Zhigong or Hunan not the name starts limited company of energy of Lin Sheng content (“ of the following abbreviation not the name is achieved forest ” ) partner.
2009, courtyard of Hunan Province Lin Ke becomes a shareholder with the technology 5 million, with Beijing University not the name was established not the name is achieved forest. 2011, not the name is achieved forest by classify Hunan Beijing University not limited company of renown biology science and technology (Hunan of “ of the following abbreviation not renown ” ) subordinate, become its board of the sources of energy piece fulcrum.
As we have learned, not the name is achieved forest it is a business of new and high science and technology that pursues biology energy research and development, production and sale technically.
So, what place did the biology diesel oil that produces by research and development of courtyard of province forest division sell? Xiao Zhigong says, basically use at the gas station on water and boiler now. Jiang Yin has these “ gas station, water area of lake of hole front courtyard also has. Boiler basically is need of company of a few large guesthouse, large-scale production. ”
Xiao Zhigong says frankly, because high oil price brings about production to be in lose money in business to manage, major company all is in stop production condition temporarily. Xiao Zhigong says, biology derv is a new live thing, accept need a process.
“ our society is an energy drive society. Biology derv is national strategy reserve, average company won’t be done, also be not done. ” Xiao Zhigong says, can insist to throw, the enterprise needs foresight, also want actual strength. #p#·ÖÒ³±êÌâ#e#
According to the plan, not the name is achieved forest always will invest 3.5 billion RMB, build to produce per year derv of 50 thousand tons of biology, produce per year derv of 300 thousand tons of biology to mediate fuel, program grows vegetable of the sources of energy 400 thousand mus and year of sale is achieved inside 5 years company of 10 billion yuan large biology energy.
Future grows vegetable of oil plants the sources of energy
Absorb the heavy metal in soil
Below current market condition, a lot of enterprises convert other sphere in succession. Why does Li Changzhu and his group continue to insist to consider? “ because this is project of reserve of national energy resources, can solve energy problem of future. ” Li Changzhu says, oil is impossible to can have forever, the sources of energy just is the lifeblood of each industry.
Accordingly, li Changzhu thinks, new energy resources is developed and use, be sure to make prospective trend. But the promotion of new energy resources, light relies on a technology to tackle key problem insufficient, still need policy support. Li Changzhu says, of biology the sources of energy discharging is very low. “ comes with zoology account, increase a ton of carbon dioxide, collect tax of content of certain greenhouse gas, grain, if using new the sources of energy, the government offers subsidy, the price of so new energy resources is not high. ”
Application is more than hereat. Effect of object height of establish of the sources of energy of “ oil plants changes national place to combine project lab ” main base oneself upon at efficient change, these plants besides change into biology the sources of energy, still can change into all sorts of material. “ does not contain the painting of formaldehyde free from contamination, clothing fabrics, even cosmetic, can do. ” Li Changzhu says, this says for oil plants wholy-owned source is used.
But Li Changzhu thinks to need to popularize most, the union that is raw material production and contaminative land processing is tasted. Wait for plant of oil plants the sources of energy through castor-oil plant, tung oil tree, Shan Cangzi is being cultivated on the land that pollutes in heavy metal, absorb the heavy metal in soil. Li Changzhu says, these plants absorb the fructification that grows after heavy metal, do not affect not only make biology diesel oil, still can produce favorable zoology effect to circumjacent water and air.
Current, this one technology already was in Chen city and other places is pilot. Li Changzhu says, this year October, can an Italian expert comes over, he will study the recycle after the heavy metal that how recruits the plant is extracted.
