| 摘 要： | 介绍了国内某炼化公司采用美国CDTECH公司催化蒸馏加氢(CDHydro/CDHDS)技术处理催化裂化(FCC)汽油的情况。CDHydro/CDHDS技术将加氢脱硫反应与催化蒸馏技术组合在1座塔器中进行。装置运行结果表明,在实现FCC汽油良好脱硫的同时还能使汽油的辛烷值保持较高数值;处理后可将轻、重汽油中硫的质量分数分别降低至5.4×10-6,38.0×10-6,将重汽油中烯烃的体积分数降低至33%。

| Abstract: | CDHydro/CDHDS technology devel- oped by CDtech Company, US, was used to hydro- treat catalytic cracking（FCC） gasoline in a refinery of China. The technology combined the hydrodesul- furization and catalytic distillation processes in one column, and realized an ideal separation between light and heavy gasoline. The results showed that it presented a good desulfurization effect without signif- icant loss of octane number. The mass fractions of sulfur in light and heavy gasoline were decreased to 5.4 × 10^-6 and 38.0 × 10^-6 respectively, and the volume fraction of olefin in heavy gasoline was de- creased to 33%. |
