1992年2月24日至27日,在美国底特律市召开了汽车工程师协会举办的国际会议。贵金属催化剂方面的文章占了很大一部分。将要公布的废气排放法对催化剂的发展起了重要的推动作用。柴油发动机用催化剂设计方面,美国集中精力研究这类催化剂中贵金属的组成方案,并找到了最佳配方。试验表明,这类催化剂有很好的控制易挥发有机物的馏分作用,并能限制
From February 24 to February 27, 1992, an international conference organized by the Society of Automotive Engineers was held in Detroit, the United States. Articles on precious metal catalysts account for a large part. The forthcoming emissions law plays an important role in promoting the development of the catalyst. In the design of catalyst for diesel engines, the United States concentrated on the composition of precious metals in such catalysts and found the best formulation. Experiments have shown that these catalysts have good control of the fraction of volatile organic compounds and can limit
