中文摘要：介绍了某石化公司炼油厂应用GARDES工艺技术建设的汽油加氢脱硫装置在生产高辛烷值脱硫汽油产品期间的关键工艺参数优化，包括分馏单元轻、重汽油切割点的选择和加氢脱硫单元各参数的优化控制。结果表明，对GARDES工艺技术中关键工艺参数进行优化和精心控制，在满足脱硫基本要求时，通过提高脱硫汽油产品的烯烃含量来达到提高研究法辛烷值（RON）的目的，可在保证脱硫汽油产品硫含量≯50mg/kg的前提下，将产品烯烃含量从约31.5%（体积分数）提高至35.0%（体积分数）左右，产品RON由89.1上升至89.6左右，上升了0.5个单位。提高了汽油池中97#乙醇调和汽油组分的脱硫汽油调和比例，增产了高辛烷值汽油产品，明显提高了全厂经济效益。
英文摘要：This paper introduces FCC gasoline hydrogenation unit application GARDES technology Optimizating of key process parameters for the production of high octane gasoline, including light, heavy oil distillation parting of cutting point selection, control of various parameters of the hydrogen desulfurization parting. Results show, optimization and careful control of key process parameters in GARDES technology, in meeting the basic requirements of desulfurization, by improving the olefin content of desulfurization gasoline products to achieve the purpose of improving the research octane number (RON), in order to ensure the desulfurization of gasoline sulfur content is less than or equal to 50 mg / kg of the premise, the product olefin content from about 31.5% (volume fraction) increased to 35.0% (volume fraction), Ron products from 89.1 increased to 89.6%, an increase of 0.5 units. The gasoline blending ratio of 97# ethanol blended gasoline component in gasoline tank is improved, and the high octane gasoline product is increased, and the economic benefit of the whole plant is obviously improved.
