摘 要: | M-PHG 催化裂化汽油(催化汽油)加氢改质-脱硫组合技术是中国石油石油化工研究院与中国石油抚顺石化公司研究院联合开发的清洁汽油生产技术,采用有机耦合催化汽油分段加氢脱硫、烯烃定向转化等核心技术,可将催化汽油在深度脱硫、降烯烃的同时保持辛烷值损失小,且对原料适应性强。为满足国VI(B)汽油质量升级要求,优化汽油产品组成,中国石油庆阳石化分公司采用M-PHG技术,对原有汽油加氢装置进行改造。改造后经过优化操作,全馏分汽油烯烃体积分数降幅可达12.1百分点,产品硫质量分数小于10 μg/g,RON损失在1.0个单位以内。改造后全厂汽油池满足国 VI(B)车用汽油质量要求。

Abstract: | The FCC gasoline hydroupgrading-desulfurization combined technology (M-PHG) is one of the best technologies to produce clean gasoline, jointly developed by PetrChina Research Institute of Petrochemicals and PetrChina Research Institute of Fushun Petrochemical Company, which organically couples core technologies of FCC gasoline stepwise hydrodesulfurization and olefins directional conversion. The technology reduces the loss of octane number of FCC gasoline during desulfurization and olefin reduction, and has good adaptability for feedstock. In order to meet the quality requirements of China national VI gasoline standard phase B and optimize the composition of gasoline products, the original gasoline hydrogenation unit was retrofitted by means of M-PHG technology in CNPC Qingyang Petrochemical Company. After optimization of operation, the average reduction of the olefin volume fraction of full-distillate gasoline reached 12.1 percentage points, the mass fraction of sulfur in the product was less than 10 μg/g, and the RON loss was less than 1.0 units. After the transformation, the gasoline pool of the whole plant meets the emission standard of vehicle gasoline in phase B of national VI standard. |
