Xinhua News Agency, Beijing, December 10th (Reporter Nan Chen), Deputy Director of the Department of Pollution Control of the Ministry of Environmental Protection Li Xinmin recently introduced at the Second International Conference on Pollution Control of Motor Vehicles, China's relevant departments will issue revised standards for unleaded gasoline for vehicles. The standard stipulates that since December 31, 2009, the sulphur content of unleaded gasoline nationwide will be reduced to 150ppm. At that time, China will eliminate gasoline with a sulfur content of 500ppm. On the same day, Xu Hui, deputy director of the Science and Technology Development Department of China Petroleum & Chemical Corporation, said that Sinopec will invest nearly 30 billion yuan to upgrade production equipment and processes, reduce the sulfur content of gasoline to less than 150ppm, and supply it to meet Euro 3 emission standards. City vehicle diesel.
In recent years, the number of motor vehicles in China has soared year after year. According to Li Xinmin, urban air pollution in China is changing from soot-type pollution to mixed pollution from soot and motor vehicles. Due to the low quality of oil used by motor vehicles in China and the low level of emissions, motor vehicles have become the major source of pollution in large and medium-sized cities.
Looking back at the changes in China's exhaust emission standards for motor vehicles, it is not difficult for people to find that we are not slow to catch up with the developed countries. From "State 0" to "State 1" and then to "State 2", "State 3" and "State 4", there are new cars required by Beijing Municipality that must be loaded with OBD (Automatic On-Board Diagnostic System), and the environmental protection department should apply to car manufacturers. Continuously increase the emission threshold. However, a contradiction also emerges: As the emission standards and the environmental performance of the vehicle are upgraded, the current situation of lagging fuel quality in China has become a major bottleneck for the implementation of energy-saving and environmentally-friendly models such as environmental protection and diesel vehicles.
For example, in recent years, reporters have received complaints from many owners of car quality problems, many of whom are caused by poor fuel quality. For example, consumers have car damage due to excessive fuel gums. Because it is difficult and difficult to find fuel suppliers to prove their problems, consumers sometimes can only detain the "carrot bowl" to the car manufacturer.
For another example, after Beijing asked the new car to be loaded with OBD, what is the problem faced by the owners is what happens in Beijing's urban areas? After running for a long distance, once the OBD alarm is caused due to unqualified fuel, according to the regulations of the environmental protection department, consumers must visit the 4S shop within a certain period of time. This undoubtedly caused consumers time and money losses.
According to the World Health Organization (WHO), about 800,000 people die each year from urban air pollution. In addition, air pollution can also cause chronic diseases, increase hospitalization, and reduce visibility. Reducing the sulfur content in fuel is the key to reducing traffic pollution emissions. Experience has shown that the U.S. clean fuel and auto projects have brought great health benefits, and they also show economic advantages. The benefits far outweigh the costs. The cumulative success of the United States Clean Air Act’s six most successful historical projects (four of which are primarily targeted at mobile sources) exceeds US$500 billion in annual revenue, while annual costs do not exceed US$20 billion.
The reporter once drove a Mercedes-Benz E-class diesel car from Paris, France, to St. Petersburg, Russia. After entering Eastern Europe, these energy-saving and environmentally friendly diesel vehicles need to be supplemented with clean diesel fuel from the accompanying tankers. According to Johannes Reifas, director of global public relations at Mercedes-Benz, after investigation, Mercedes-Benz Eurasia's tour passes through countries with diesel fuel containing up to 3,300 ppm sulfur and water and sand. In some parts of China, the sulphur content of diesel exceeds 1000ppm, while the European clean diesel standard is 10ppm.
According to Huang Gang, deputy general manager of Dongfeng Commercial Vehicle Co., Ltd. Dongfeng Automobile Co., Ltd., the quality of fuel oil for vehicles currently sold on the market cannot fully meet emission requirements, leading to a serious decline in the emission levels of in-use vehicles that meet emissions regulations. Taking No. 0 diesel as an example, the sulfur content of commercially available diesel in most parts of the country is 1500 ppm.
It is not easy to achieve a reduction in fuel sulfur content. China's large amount of imported crude oil has high sulphur content. Sinopec imported crude oil from January to October 2006 had an average sulphur content of 1.11%, while the company imported crude oil in 1999 with a sulphur content of only 0.17%. Xu Hui, deputy director of the Science and Technology Development Department of China Petroleum & Chemical Corporation, said that the cleanliness of fuel must meet the challenges of processing crude oil.
Tang Dagang, the motor vehicle's sewage monitoring center of the State Environmental Protection Administration, suggested that it is necessary to formulate the four-phase vehicle diesel specification as soon as possible and give the petrochemical sector sufficient time to prepare. The recommended stage 4 sulfur content is less than 50ppm, and the 5 stage sulfur content is less than 10ppm. It was started on January 1, 2008 and January 1, 2011, respectively, on January 1, 2011 and January 1, 2013. Implemented nationwide.
The Ministry of Commerce recently released the Measures for the Administration of the Refined Oil Market and the Measures for the Administration of the Crude Oil Market, which came into effect on January 1, 2007, and opened the right to wholesale domestic crude oil and refined oil products. According to relevant persons from the Ministry of Commerce, after the implementation of the above two measures, it will break the country’s unified configuration of crude oil resources and the centralized wholesale and refined oil products of PetroChina and Sinopec, allowing qualified companies to engage in wholesale operations of crude oil and refined oil in China. The oil market will gradually form a pattern in which large state-owned oil companies, multinational oil companies, and social management units will participate in competition.
The reporter believes that after the disappearance of the threshold, domestic petrochemical enterprises should improve the quality of fuel as soon as possible and increase the strength to compete with multinational oil companies. The domestic fuel price must be in line with international standards, and the quality of combustible oil must be in line with international standards as soon as possible.
