摘要
介绍了目前正在应用或开发的一些汽油脱硫新技术 ,其中吸附法脱除汽油中含硫化合物的投资成本及操作费用很低 ,是一项非常具有吸引力的脱硫技术。根据我国汽油的生产情况 ,应该着重考虑催化裂化汽油脱硫 ,结合实际情况 ,采用催化裂化过程直接脱硫、吸附脱硫等多种方法降低汽油中的硫含量 ,以满足新配方汽油的要求。
Worldwide effort has been made to lower the sulfur level of gasoline significantly as part of continuing effort to reduce air pollution. New processes for gasoline desulfurization were briefly reviewed in which adsorption desulfurization is an attractive technology for its low investment and operation costs. In accordance to the composition of domestic gasoline, FCC naphtha should be highlighted to reduce sulfur content. Direct desulfurization in FCC process and adsorption desulfurization, etc. are proposed to reduce the sulfur level in FCC naphtha for meeting the requirement of new formulation gasoline.
