生产低硫汽油的新技术

介绍了我国及欧美等国家车用汽油标准中对硫含量的规定，以及降低催化汽油硫含量的几种工艺方法，特别是新发展起来的FCC脱硫助剂、FCC脱硫催化剂和膜分离等技术。采用新的脱硫技术可以在不同程度上降低催化汽油的硫含量。适应不同的脱硫要求，为炼油厂生产低硫汽油提供了更多的技术选择。

Technologies for Low-sulfur Gasoline

This paper presents the sulfur regulations for automobile gasoline in the different countries such as the P.R.China ,the U.S. and EU countries, and several existing or new technologies for reducing the sulfur concentration in FCC gasoline,especially new developed processes,such as FCC SR additives,FCC SR catalysts and membrane technology.The sulfur content in FCC gasoline can be reduced at different degrees by using any new technology,and they can meet different requirements of sulfur reduction,which provides more options for production of low sulfur gasoline.
