The commercial application results of 0.9 Mt/a OCT-M FCC naphtha desulfurization unit of Jinling company show that the research octane number (RON) of “sulfur-free” gasoline(? (S)≯10 μg/g) is reduced 2.5 unit. OCT-MD process can reduce sulfur and mercaptan of light cut naphtha, the RON of OCT-MD process sulfur-free gasoline(? (S)≯10 μg/g) is reduced 1.7 unit. Operation results of OCT-M plant for producing sulfur-free gasoline in Jinling company show that sulfur mass fraction in the product is less than 10 μg/g, the loss of RON is less than 1.8 unit. After light cut naphtha(LCN) extraction unit was put into production of OCT-M unit, the sulfur content of LCN was reduced from 43.1~74.2 μg/g to 15.4~28.6 μg/g ,the FCC naphtha and product sulfur contents of OCT-M unit were 99.1~261.0μg/g and 9.3~13.2μg/g, respectively, RON loss was 0.7~1.5 unit. So, compared with without LCN extraction desulfurization, the RON loss of OCT-M unit decreased about 1.0 unit.
