提升油品质量、降低机动车污染物排放,对改善我国空气质量至关重要。通过隧道试验测试了道路机动车污染物排放水平,从我国8大城市加油站收集的汽柴油样品实测了其硫含量和烃类组成等指标,用先进的烟雾箱系统模拟了汽油车和柴油车尾气直接排放和二次反应生成的颗粒物,并探讨了机动车尾气对细颗粒物(PM_(2.5))的综合贡献与油品之间的关系。在分析我国油品升级所需的脱硫、重整、加氢等技术需求的基础上,初步估算了我国汽柴油全面升级的直接投资需求。文章也揭示了突破柴油发动机和柴油深加工技术对我国机动车减排的重要意义。 |

Upgrading fuel quality to lower vehicle emission is vital to improve air quality in China. We conducted tunnel tests to evaluate emission of air pollutants from on-road vehicles, collected gasoline and diesel oil samples from gas station in China’s eight large cities and analyzed their quality index including sulfur contents and composition of hydrocarbons, studied primarily emitted and secondarily formed aerosols from vehicle exhausts by smog chamber simulation, and further explored the relationship between fuel quality and vehicle’s overall contribution to PM_(2.5). Based on the analysis of the technical requirements of desulfurization, reforming and hydrogenation for upgrading fuel quality, the costs of upgrading gasoline and diesel oil quality in China was preliminarily estimated. The technological breakthrough in diesel engine manufacturing and diesel oil deep-processing is also of great importance in cutting China’s vehicle emission. |
