GARDES-II汽油加氢精制技术的工业应用

为生产国VI（A）标准汽油，中国石油兰州化工研究中心与福州大学、中国石油大学（北京）在原有汽油加氢GARDES技术的基础上，对原催化剂进行改进，开发了GARDES-II技术，并在中国石油宁夏石化公司1.2 Mt/a汽油加氢脱硫装置上工业应用。标定结果表明:经GARDES-II技术处理后，FCC汽油的硫质量分数由58 μg/g降低到8.1 μg/g;烯烃体积分数由40.8%降低到29.8%，降幅为11.0百分点;汽油的研究法辛烷值损失为1.2个单位。与原GARDES技术相比较，GARDES-II技术降烯烃能力有很大幅度提高。

INDUSTRIAL APPLICATION OF GASOLINE HYDROFINING TECHNOLOGY GARDES-II

In order to produce the China VI compliant gasoline, China University of Petroleum（Beijing），Fuzhou university and PetroChina Lanzhou petrochemical Research Center developed the FCC gasoline hydrodesulfurization GARDES–II technology based on the previous GARDES technology and relative catalysts. The new GARDES-II technology and the catalysts were applied in PetroChina Ningxia Petrochemical Company 1.2 Mt/a FCC gasoline hydrodesulfurization unit. The industrial calibration results showed that the sulfur content of FCC gasoline reduced from 58μg/g to 8.1μg/g, and the olefin volume fraction decreased from 40.8% to 29.8% and the RON loss of gasoline was 1.2. Compared with the GARDES technology, GARDES-II technology showed higher olefin reduction ability.
