| New Gasoline Standard to Reduce Sulfur Levels |
| Adjust font size: |
The Chinese government will reduce sulfur levels of lead-free gasoline to 150 parts per million (ppm) in the revised gas standard. The move would help improve air quality, an environmental official said. The revised lead-free gas standard, to be announced by the end of this year, will drive gas with sulfur levels of 500 ppm out of market on Dec. 31, 2009, said Li Xinmin, deputy director of the pollution control department of the State Environmental Protection Administration (SEPA), at a symposium on automobile pollution control. The new standard would meet the Euro-III emission norm, which constrained sulfur levels to 150 ppm maximum. "Automobile emissions have become a major factor of urban pollution, " Li said. Statistics from the SEPA show In the first half, sulfur dioxide emissions increased by 4.2 percent, from the same period a year earlier. Sinopec, the China Petroleum and Chemical Corporation, one of the major petroleum companies in China, announced plans to invest 30 billion yuan (US$3.75 billion) in reducing the sulfur levels in gasoline. Xu Hui, deputy director of Sinopec's technology development department, said some companies were already capable of producing gas with sulfur levels less than 150 ppm. It would take a lot of effort to meet the new gas standard, Li Xinming said, adding that currently only gas provided in Xu said gas producers would find it difficult to reduce sulfur levels as the sulfur levels in imported crude oil were high: an average of 1.11 percent of the imported oil by Sinopec in the first ten months, whereas sulfur levels of imported oil in 1999 was only 0.17 percent. The high sulfur level of crude oil would pose a challenge to making clean auto fuel, Xu said. (Xinhua News Agency December 8, 2006)
