Recently, a research group of the School of Life Science at Nanjing University announced that they have successfully extracted biodiesel from a salt-tolerant oil plant that is suitable for growing on non-agricultural land (saline-alkaline). This is a scientific and technological achievement for the development of low-cost raw materials for the development of biodiesel. Undoubtedly, there is no doubt that the oil price has been rising at a high level. It also unveils a response from the industry. It also unveiled today's first renewable energy in Jiangsu and the third session of solar energy applications and technologies. exhibition. The reporter interviewed Dr. He Xiaoxiang of the School of Life Sciences of Nanjing University Nanjing University yesterday. Dr. He Xiangxiang demonstrated to reporters the biodiesel production process. First, a seed called seashore mallow was placed in a prepared press. As the machine turned golden yellow liquid flowed out like a daily cooking oil. , and then collect it in a prepared container. After a certain amount of time, a chemical agent is added for constant stirring. After a while, the “diesel†of the internal combustion engine can be used. The whole process is very simple. It is said that such "diesel" can only "produce" 40 liters a day in the laboratory. Dr. He Xiangxiang told reporters that biodiesel is not only a renewable green energy, but also has good lubrication and combustion properties. Although there are so many advantages, its application in China is still relatively small, and the industrialization process is far from abroad. The reason for this is, on the one hand, the current problem of biodiesel raw materials. The price of biodiesel is subject to the price of raw materials, and the high price of raw materials makes the price of products not competitive in the market. Now in the cost of biodiesel, the cost of raw materials accounts for more than 60%, and the price of raw materials is the biggest bottleneck of biodiesel in domestic industrialization. At present, the extraction of biodiesel in the world mainly consists of three categories: herbaceous plants, woody oil species, and aquatic oil plants. The common herb oil crops mainly include rapeseed, soybean, peanut, cottonseed, and flax, among which rapeseed is the most widely used. The common woody oil plants include palm, glossy tree, camellia, coconut tree and so on. However, the cultivation of these plants requires a large amount of arable land and forest land. Because of this, due to the shortage of per capita arable land in China, the planting of these plants has been restricted. “The idea of ​​our research is to address the problem of raw material development for biodiesel. Instead of competing with people for oil or competing with crops, we should study salt-tolerant plants like seashore mallow as raw material,†said Dr. He Weixiang. “ Another objective of this study is to solve the problem of land reclamation on the beach, so that it can serve two purposes. "At present, the refined fuel (laboratory) refined by the project has been tested in the authority of Sinopec. "The greatest advantage of planting salt-tolerant oil plants is low cost. The saline-alkaline lands on the beach are marginal lands. Moreover, this salt-tolerant plant is perennial, does not require annual planting, and has very little involvement in the growth process." “At present, we have successfully tested the coastal saline-alkaline beaches in Tianjin, Dalian, Zhejiang, and Jiangsu, and the next work is mainly to further increase the oil content and the production per unit area, and to select and train new ones that can be industrialized as soon as possible. Variety," said Dr. He Xiangxiang. If we can overcome this bottleneck, the domestic industrialization of biodiesel will certainly take a big step in the supply of raw materials. In the interview, Dr. He Zuoxiang told reporters that the state's technical standards for biodiesel have not yet been formulated, and a series of related work on industrialization and marketization of biodiesel has not been carried out, and technical standards such as production, storage and transportation are also lacking. These have brought inconvenience to the promotion and application of China's biodiesel, and hope that the problems in this area can be resolved early to achieve the real industrialization of biodiesel.
Inorganic salts are salts in inorganic compounds, formerly known as minerals, generally accounting for only 1% to 1.5% of the fresh weight in biological cells. At present, more than 20 kinds of elements have been found in the human body. Among them, a large number of elements are Ca, P, K, S, Na, Na, Cl, Mg, trace elements are Fe, Zn, Se, Se, Mo, Mo, F, Cr, Co, I and so on. . It includes more than 1000 inorganic chemical products, including boric acid, chromic acid, arsenic acid, phosphoric acid, hydrobromic acid, hydrofluoric acid, hydrocyanic acid and other inorganic acids, barium, chromium, magnesium, manganese, calcium, lithium, potassium hydroxide and other inorganic bases, as well as nitrides, fluorides, chlorides, bromides, iodides, hydrogen. Compounds of elements such as carbides, cyanides, carbides, oxides, peroxides, sulfides and other elements such as potassium, sodium, phosphorus, fluorine, bromine and iodine.
They can be divided into three categories:
(1) The processing technology of mineral processing products is similar to hydrometallurgical process, but the difference lies in the final product. The former is usually a compound, while the latter is mostly metallic matter. The technological process generally includes crushing and processing of ore, mixing of various materials, calcination, leaching, filtering, refining, evaporation (or distillation), crystallization, separation, drying and other processes.
(2) Inorganic synthetic products are the process of making new materials from basic chemical raw materials, generally using precipitation, oxidation and reduction, electrochemical method, high temperature and high pressure reaction, catalytic reaction, ion exchange method, etc.
(3) Inorganic Fine Chemicals are mainly used to produce materials with new physical structures, such as crystal structure, grain size, specific surface area, porous, pile density and other physical properties of different substances. Therefore, the use of ultra fine technology, molding technology, activation technology and surface treatment technology.
