加氢焦化石脑油非临氢改质技术的工业应用

COMMERCIAL APPLICATION OF UPGRADING TECHNOLOGY FOR HYDROGENATED COKER NAPHTHA WITHOUT THE PRESENCE OF HYDROGEN

石油化工科学研究院开发的石脑油非临氢改质技术在中国石化塔河分公司70kt/a石脑油异构化装置上的工业应用结果表明,加氢焦化石脑油非临氢改质处理后,可得RON为83.2、烯烃质量分数为1.83%的稳定汽油以及C_3～C_4烷烃质量分数为92.55%左右、烯烃质量分数低于10%的液化气,同时副产少量干气;稳定汽油和液化气的收率分别为71.38%和26.48%,达到了多产稳定汽油、少产液化气的目的。稳定汽油可作为品质优良的汽油调合组分,液化气脱硫后可作为车用液化气。

An upgrading technology for hydrogenated coker naphtha without the presence of hydrogen was developed by Research Institute of Petroleum Processing and it was applied in the 70 kt/a naphtha isomerization unit of SINOPEC Tahe Petrochemical Company. The commercial application results showed that the yields of stabilized gasoline and LPG were 71.38% and 26.48%, respectively, which reached the goal of producing more stabilized gasoline and less LPG. The stabilized gasoline having a ROAr of 83.2 and an olefin content of 1.83% could be used as high quality gasoline blending component, the LPG having C3-C4 paraffin content of 92.55% and olefin content less than 10% could be used as automobile LPG after desulfurization.
