摘 要: 介紹了撫順石油化工研究院和大連理工大學(xué)合作開發(fā)的OTA(Olefin to aromatics & alkylates)全餾份催化裂化（FCC）汽油降烯烴技術(shù)，利用OTA 技術(shù)對(duì)全餾份FCC汽油進(jìn)行了加氫改質(zhì)處理，通過烴類烷基化、 芳構(gòu)化、 異構(gòu)化和少量裂化等烴類轉(zhuǎn)化反應(yīng)， 使烯烴含量大幅度降低， 同時(shí)產(chǎn)物的辛烷值損失較低， 汽油收率高。 結(jié)果表明： OTA技術(shù)FCC汽油脫硫率約為70%、 烯烴飽和率為60%~77%， 抗爆指數(shù)(R+M)/2損失0~1.2， C5+汽油液收92.0%~97.0%， 化學(xué)氫耗為0.20%~0.40%。

Abstract:The OTA technology jointly developed by Fushun Research Institute of Petroleum Processing of SINOPEC and Dalian University of Technology was introduced briefly. The OTA technology upgraded full range FCC gasoline by alkylation, aromatization, isomerization and little cracking can deeply reduce olefin level in FCC gasoline. On the other hand, the road octane number( (R+M)/2) loss is very low, gasoline yield is high. The test results indicate that the desulfurization and olefin removal of FCC gasoline of OTA are about 60%～77% respectively, road octane number( (R+M)/2) loss is 0～1.2 units, C5+ gasoline yield is 92.0%～97.0%, and chemical hydrogen consumption is 0.20%～0.40%.
Key words: fluid catalytic cracting(FCC) gasoline; aromatization; olefin removal; desulfurization; road octane number( (R+M)/2)
