最近，美国的科学家研制了一种简单的金属过滤器，使用这种过滤器可以方便地去除石油中所含的硫和重金属。该项技术不仅解除了石油工业中最大的环境污染问题，而且也为蕴藏量巨大而品质不好石油的开采利用打开了一扇门。与石油金属过滤器去除硫相比，原有的去硫方法则成本非常? Recently, U.S. scientists have developed a simple metal filter that can be used to easily remove sulfur and heavy metals from oil. The technology not only lifted the biggest environmental pollution problem in the oil industry, but also opened the door to the exploitation of oil with huge reserves but of poor quality. Compared with the oil metal filter to remove sulfur, the original desulfurization method is the cost?
