摘　　要：介绍了同时多产液化气和柴油及降低汽油烯烃含量的工艺技术(MGD)在催化裂化(RFCC)装置上的工业应用。优化操作条件,在提高反应温度、提高剂油比、提高催化剂活性等措施后,可以明显改善产品分布,提高产品质量。应用结果表明:MGD技术在装置上应用前后相比,液化气产率可提高3～6个百分点,柴油产率提高4～6个百分点,(液化气+柴油+汽油)产率相差不大,柴汽比提高了0.2以上。汽油的辛烷值(RON)由90.3提高到91,汽油的烯烃的质量分数(荧光法)由45.2%降低到33%,并且可以灵活调整生产方案,具有明显的经济效益和社会效益。The applications of the Maximizing Gas and Diesel Technology(MGD), which could produce gasol and diesel, and reduce the alkene content of gas, in the residue fluid catalytic cracking(RFCC) was presented in this paper.In response to the optimization of operating conditions, such as measures to raise the temperature, increase the agent-oil ratio, or improve the catalyst activity, the distribution of products and the product quality got significantly improved.The results of application showed that, compared with the former device without transformation, MGD technology increased productive rate of liquefied petroleum gas(LPG) by 3～6 percentage points and that of diesel by 4～6 percentage points, also simultaneously with the raising of the diesel-gas-ratio up to 0.2 and the slightly changing of those overall light liquid yield.Meantime, RON was elevated from 90.3 up to 91, and the naphtha olefin content(fluorimetric method) was reduced from 45.2% to 33%.With the high flexibilities of operation and product variety, MGD technology has visible economic and social benefits.
