车用柴油新标准的硫含量修订及其影响

新标准GB19147-2013《车用柴油（Ⅳ）》是根据我国当前经济发展实际情况,环保的现实要求,在参考欧盟实施欧Ⅳ阶段排放时所制定的车用柴油标准,对原GB19147-2009《车用柴油》标准中硫含量等项目指标进行了修订.硫含量由原来质量分数不大于350mg/kg,修改为现在的质量分数不大于50 mg/kg.新标准对硫含量指标的修订,对炼油企业在车用柴油生产技术的改进、硫含量检测仪器的更新、检验人员的培训与提高都将产生影响;也为早日与国际先进标准接轨、降低车用柴油中的硫含量、减少汽车尾气对大气造成的污染及减少雾霾天气的产生创造了条件.

Revision of sulfurcontent in new automobile diesel standard and its impacts

According to our present development of economy and actual requirement of environment protection, the new standard GB 19147--2013 ＂Automobile Diesel Fuels IV＂ is a revision of the original GB 19147--2009 ＂Automobile Diesel Fuels＂ on items such as sulfur content, referred to automobile diesel fuels standard developed by European Union during its execution of Stage IV emission. Sulfur content mass fraction in automobile diesel was changed from no more than 350 mg/kg to no more than 50 mg/kg. The new standard＇s revision on sulfur content will have impacts on technological improvement of automobile diesel manufacturing in oil refineries, renewal of sulfur content inspection instruments, and training of inspection staff. It also paves ways for catching up with advanced international standards, decreasing sulfur content in automobile diesel, mitigating air pollution caused by vehicle exhaust and reducing hazy weathers.
