超低硫清洁汽油生产方案的选择及工业应用

环保法规的日益严格使超低硫清洁汽油的生产备受关注。本文着重分析了S-Zorb汽油吸附脱硫技术与其他脱硫技术的区别及优势，同时对该技术在国内某炼油厂的工业应用情况进行了介绍。工业应用表明：采用S-Zorb汽油吸附脱硫技术后，催化裂化汽油的硫含量从276．0μg/g培降至7．7μg／g，辛烷值损失仅为0．4个单位，精制汽油总收率为99．01％，各项技术指标基本在设计范围内。

The Selection of Production Method and Industrial Application of Clean Gasoline with Ultra Low Sulfur Content

Production of the clean gasoline with ultra low sulfur content is concerned with the stringent environmental requirements increasingly. Advantages and characteristics of the S-Zorb adsorption desulfuriza- tion technology are analyzed emphatically, and industrial application of the S-Zorb in a refinery of China introduced. The results of industrial application show that the sulfur content of gasoline made from fluid catalytic cracking is reduced 276.0 μg/g to 7.7 μg/g, the loss of octane value to be only by 0.4 unit, the total yield of refining gasoline to 99.01%, and the technical parameters being in design range basically.
