The Morning Post reported, "That is it!" Ji Jianping, president of Zhijiang College of Zhejiang University of Technology, took out a test tube containing a pale yellow liquid that glowed with beautiful luster under sunlight.

Yesterday, in an open space in the Industrial Park in Tangxi Town, two workers poured 10 litres of pale yellow liquid that had just been put on the production line into truck fuel tanks. Soon, the truck drove out. "Biodiesel was successful. Truck speed was as fast as regular diesel." Vice President Wang of Hangzhou Zhengguang Resin Co., Ltd. was pleased to report to reporters. Over the past few months, Zhengguang Company has continuously added this yellow liquid to trucks and bulldozers. The result was more exciting than ever.

"Biodiesel-powered cars have the same power as mineral diesel, but they emit 50% less harmful pollutants than fossil diesel." Ji Jianbing took the report issued by the Zhenhai Petrochemical Quality Inspection Center: "Our biodiesel Has reached the German technical indicators."

In order to develop the production technology with an annual output of 50,000 tons of biodiesel, Ji Jianping took the team to work overtime; the head of the Institute of Biotechnology of the Provincial Academy of Agricultural Sciences, headed by the hot sun, contacted Tongxiang to plant rapeseed land because it It is the raw material of biodiesel. How much magic does biodiesel really make these elites so persistent?

Rapeseed oil "fit" into biodiesel

In 2002, when Ji Jianping returned from study abroad, the situation was so keen that he decided to study "inexhaustible, inexhaustible" biodiesel.

The waste oil, cooking oil, vegetable oil, etc. on the table can all become biodiesel in Ji Jianbing's laboratory. But in the end what kind of raw materials will be selected, will biodiesel eventually reach the civilian population? Solving this difficult problem was accidental. Last year, Ji Jianbing went to Beijing on business and listened to an academician. A Zhejiang scholar, Chen Jinqing, was studying a new variety of high-yield, high-oil rapeseed that could be used as a raw material for biodiesel. Chen Jinqing was commissioned by the Ministry of Science and Technology. Participated in the drafting of the National Eleventh Five-Year Biomass Energy Plan in Beijing.

Two people soon met, and Chen Jinqing had just cracked the raw material problem of biodiesel.

Biodiesel is the national eleventh five-year science and technology project. In October of last year, experts participating in R&D were stuck with a problem: the price of rapeseed oil was more than 5,000 yuan a ton, while ordinary diesel oil was only 5,000 yuan per ton. To make rapeseed oil into biodiesel, a series of The cost of processing procedures is not small. As such, industrialization is simply not realistic.

At this critical juncture, Chen Jinqing came up with an exhilarating approach: rapeseed oil contains a kind of fatty acid called "erucic acid," which is a valuable green chemical raw material. It costs more than 20,000 yuan per ton. "The high added value of 'erucic acid' is used to compensate for the high cost of oil investment," Chen Jinqing suggested. "According to our thinking, the economic efficiency of enterprises has gone up. It is profitable. There is enthusiasm for production. Farmers have money to earn. Willing to grow rapeseed; consumers can also use cheaper biodiesel." Chen Jinqing said.

Industrialization becomes possible

After Chen Jinqing has cultivated rapeseed, Ji Jianbing will react with the refined oil and methanol, convert it to biodiesel 1:1, and directly pour it into the diesel engine. Then he can use it. The technicians were tested on tractors and bulldozers and the results were very good. In foreign countries, there are successful examples of using biodiesel in automobiles.

Zhegong University's biodiesel technology has applied for a national patent and has complete intellectual property rights. Internationally, there are many methods for producing biodiesel, but Zhegongda's technology can reduce the reaction time by 4 times under normal temperature and pressure. "Originally, people responded for one hour. Now we only need 15 minutes. The same time, the shorter the reaction time, the less equipment needed and the smaller the factory area. It suits the actual needs of Zhejiang," says Ji Jianbing.

Gaining access to land

Although there are brilliant ideas, things are not as smooth as people expected. Chen Jinqing has just started to choose a kind of genetically modified rapeseed called “Super Oil No. 1” and “Super Oil No. 2” as raw materials. Both canola produce at least 50% of oil and 50% of erucic acid. However, because of the sensitive nature of genetic modification, no "life permit" has been granted.

Everyone did not feel discouraged, but also locked the raw materials No. 2 "candidates" - the "hybrid No.2" developed by conventional hybridization technology. Although the oil content and erucic acid were all reduced by 20%, they did not encounter any trouble in the approval process.

At present, several tons of "Youza No. 2" rapeseed are ready. In September, it is time to plant rapeseed in one year, but everyone has encountered a problem: the land has not yet been negotiated.

Yuhang, Tongxiang... They can run anywhere they can run. “Looking for a few thousand mu of land to allow rapeseed to settle down is not easy, but we also believe in hard work and will eventually resolve it,” said Chen Jinqing.

Energy Saving and Environmental Protection - Two Major Benefits of Biodiesel

On August 28, Mr. Zhang, a Zhangzhou driver, ran a number of gas stations in buses and did not add diesel. The large number of cargo ships in Yuhang Tangqi was collectively transported. Diesel fuel supply was one of the reasons.

What is the result of biodiesel? There is no need to break legs for diesel, there is less pollution in the exhaust, the air is cleaner, and the price is affordable... Currently, Ji Jianbing is researching and developing technologies that can produce 50,000 tons of biodiesel. Once successful, It will be able to meet 1/30 of the total diesel consumption in Hangzhou in one year.

By the end of July this year, only 1.17 million vehicles of various types including motor vehicles and other vehicles in Hangzhou had been growing at a rapid rate of 22% per year. Relevant departments expect that Zhejiang Province will consume 8 million tons of diesel oil this year; the total consumption of diesel oil in Hangzhou this year is about 1.5 million tons. Experts are optimistic that biodiesel industrialization will eventually change the energy shortage in Zhejiang.

Zhang Qingyu, a teacher from Zhejiang University, once led a team to investigate exhaust emissions. Every day, car exhaust is equivalent to manufacturing one ton of toxic benzene to Hangzhou City. Tail gas pollution accounts for 40% of Hangzhou's gas pollution. Exhaust gas has a strong carcinogenic effect, long-term exposure can cause chronic poisoning in humans. The exhaust gas is also associated with photochemical pollution that pollutes the atmosphere.

The use of biodiesel in the exhaust gas than 50% of the use of mineral diesel, "development and production of biodiesel, no waste gas, waste residue, and waste water treatment can be recycled, truly zero emissions." (0310501)

40% Gasoline Demand in Brazil

This year, Brazil will reach the balance of energy import and export for the first time. The ethanol fuel extracted from sugarcane has replaced 40% of the country's gasoline demand, and its price is far lower than that of gasoline. Ethanol fuel costs only two dollars per gallon, which is 1.7 dollars lower than gasoline.

In 1975, 75% of Brazil’s energy needs came from abroad. To change this situation, the Brazilian government launched an ethanol fuel project. The government subsidizes farmers who grow sugar cane and requires all towns with more than 1,500 people to install ethanol pumps for ethanol production.
