摘要： 介绍了中国石油石油化工研究院开发的催化裂化汽油加氢脱硫（DSO）技术的特点及在玉门炼油厂320 kt/a加氢装置上工业试验的情况。标定结果表明：处理玉门高烯烃含量FCC汽油（烯烃体积分数57.5%）时，原料平均硫含量从320.3 μg/g降到59.3 μg/g，脱硫率为81.5%，RON平均损失0.7个单位，配合炼油厂其它汽油调合组分可直接调合硫含量小于50 μg/g的满足国Ⅳ标准的清洁汽油。

Abstract: A FCC gasoline hydrodesulfurization technology (DSO) was developed by PetroChina Petrochemical Research Institute and its commercial trial was carried out on a 320 kt/a hydrotreating unit of Yumen Refinery successfully. Performance test results showed that the sulfur content of FCC gasoline (having high olefin volume content of 57.5%) was decreased from 320.3 μg/g to 59.3 μg/g, i.e. a sulfur removal rate of 81.3%, and the average RON loss was only 0.7 units. This treated gasoline could be blended with other gasoline components of said refinery to form a gasoline product meeting the requirements of National Standard Ⅳ for clean gasoline (sulfur content less than 50 μg/g).
Key words: gasoline, hydrodesulfurization, octane number, catalytic cracking
