Biodiesel Production Line factory
Know newly
Perhaps which day, the health care that we take is tasted even if power plant litter produces.
This is a thought of the thrill through when the reporter interviews Wang Jiang’s researcher.
Recently, the message that scientists of a “ our country discover to chlorella ‘ eats the azotic oxide in ’ flue gas and carbon dioxide ” aroused the curiosity of a lot of people.
What is chlorella? What does its “ eat oxide of the nitrogen below ” and carbon dioxide to become again? On November 27, reporter of daily of science and technology is taking these question, interviewed a the Chinese Academy of Sciences Wang Jiang of aquatic biology institute’s researcher.
Proved “ biology decreases a ” feasibility first
In recent years atmosphere mist haze affected the health of people and life badly, azotic oxide is the main inducement of acid rain and mist haze. Azotic oxide discharged our country 2016 gross is as high as 23 megaton, rank the world the first.
The technique that eliminates azotic oxide calls “ to take off saltpetre ” , because azotic oxide can follow water reaction to make nitric acid root, inferior nitric acid root, as it happens is small alga available azotic nutrition, through small alga so education can eliminate azotic oxide pollution, develop new-style biology to take off saltpetre technology. The small alga live thing that achieves from this pledges by-product can serve as the origin of albumen, oil plants, satisfy the raw material requirement of the industry such as the sources of energy of aquatic product feed, biology.
The carbon in small alga biomass and azotic element content are occupied respectively 50% and 10% the left and right sides. Small alga is earthly admiral carbon dioxide and inorganic nitrogen translate into a kind of light with organic matter highest efficiency closes microbial, be known as is the ” of factory of efficient “ biology that moves by sunshine drive.
Can take a power plant with installing ” of factory of this “ biology, let small alga “ eat the azotic oxide in flue gas of industry of ” come off work and carbon dioxide, implementation carbon decreases a platoon and reduce environmental pollution, can produce the raw material that gives biology the sources of energy and product of high additional cost again at the same time, realize “ one Shi Shuangdiao ” ?
The Wang Jiang that alga biology studies was engaged in 8 years in abroad, as the the Chinese Academy of Sciences aquatic biology institute introduces 100 people of “ to plan ” researcher, went back to the motherland in July 2010 establish small alga to study a group, begin to throw this research.
2014, first paper takes the lead in be being published in international environment to learn a territory top class periodical ” environmental science and technology ” on. This research is thought to the feasibility ” of product of high additional cost is produced while “ proved small alga is used at industrial contaminant to decrease a platoon first in the world. #p#·ÖÒ³±êÌâ#e#
Had entered difficulty of experiment of a road industry
7 years of time, king powerful group turned the tentative plan into industrial feasibility stage by stage, they had taken hard course among this.
It is alga is planted above all problem. In various alga, what alga is planted many what “ eats, the much ” that produces again?
Chlorella is alga of a kind of globose one-celled fresh water, diametical 3—8 micron, progenitive rate exceeds strong. Wang Jiang says: “ chlorella is the fastest 2 hours can breed generation, that is to say two hours can turn over its biomass, grow nature of fast work efficiency is tall also. ”
The course is chosen ceaselessly, the chlorella that obtains finally rose respectively than groovy chlorella grease and biomass productivity 39% with 35% , the rate that take off saltpetre can amount to 96% above.
Be aimed at azotic oxide not dissolve the problem at water, wang Jiang’s group passes Rong Junfeng of as petro-chemical as Chinese petrifaction scientific academy to teach collaboration, innovation sex ground built flue gas carbon dioxide and azotic oxide resource to change plan, put forward two footwork biology to take off the theory of saltpetre, the absorption that absorbs unit through azotic oxide namely is secured and the biology with small alga unit education changes photograph incorporation, implementation carbon dioxide and azotic oxide resource change a loop to use. Small alga biology put forward to take off saltpetre route chart on this foundation 1.
The new difficult problem that level tries to encounter in entering is how to be fostered discharge the small alga that match with industrial flue gas. The industrialization that passes one stage is optimized, chose barmy way finally, of 100 tons of class ferment the system can solve medium or small the azotic oxide that arranges a business reduces a problem, cover an area of only 200 square metre.
On this foundation, the combination that the group takes off production of product of saltpetre, high additional cost and biology derv preparation to small alga biology further produces craft to undertake improvement, the manufacturing technology that put forward to optimize 2 edition. With Rong Junfeng the professor cooperates to change Shijiazhuang refine to changed a branch to build home in Chinese stone first refinery flue gas is petroliferous small alga biology reduces a demonstrative unit, formed reserve of technology of whole set of derv of small alga biology.
Use small alga to may extract prandial replenishers
Carry systematic research, researcher explain is clear and petroliferous the biologic base that small alga uses at industrial flue gas to decrease a platoon, proved small alga changes the applied value of the domain and feasibility in biology of industrial flue gas, finished Cong Zao to plant library construction is collected to efficient and dimensions breed aquatics, feebleminded bad news close and the development of the complete technology catenary such as alga oil extraction, successful preparation the derv of small alga biology that accords with national level, compose built small alga the solid carbon, loop economic system that takes off saltpetre and raw material to be used integratedly and the complete and patent network that include 26 inventions patent. #p#·ÖÒ³±êÌâ#e#
The raw material that “ small alga regards biology as the sources of energy is opposite for lower end. ” Wang Jiang says, rich protein, fat is contained in small alga cell kind, the nutrient composition that the high price such as a variety of carotene of alga polysaccharide, β- , inorganic elements is worth and industrial chemicals. If use small alga to extract prandial replenishers, value will be higher.
“ but if say the prandial replenishers that is production of ’ of litter of ‘ of petrifaction flue gas, everybody may be not accepted. ” Wang Jiang says, so next, industrialized seminar key is put in litter of raw material power plant to handle circular economy technology integratedly to consider. Be based on this, the group put forward small alga biology to take off saltpetre route chart further 3 edition (see figure below) .
Wang Jiang says, it is on geology history, the prosperity of small alga is the basis that forms fossil the sources of energy, so small alga propped up subterranean of fast ancient bury modern petro-chemical system. In future, the mankind or will be based on small alga to foster compose to build new-style loop economic system, obtain biology the sources of energy, biology radical through refine of small alga biology but product of degradation material, careful chemical, healthy medicine, the loop that realizes carbon and nitrogen is used, solve industrial pollution to arrange brought environmental issue.
