欧美汽油含硫规范正面临新的挑战。按照欧盟汽车 油料计划 ,汽油含硫量已从 1999年 5 0 0 μｇ/ｇ减小到 2 0 0 0年汽车 油粒计划Ⅰ的 15 0 μｇ/ｇ ,并将进一步减少到 2 0 0 5年汽车 油料计划Ⅱ的 10～ 5 0 μｇ/ｇ。美国 2 0 0 0年汽油含硫已降到 338μｇ/ｇ ,ＣＡＲＢⅡ
Sulfur standards in Europe and the United States are facing new challenges. According to the EU auto fuel plan, the sulfur content of gasoline has been reduced from 500 μg / g in 1999 to 150 μg / g in 2001 and will be further reduced to 2.55 years Automotive fuel plan Ⅱ 10 ~ 50 μg / g.
