摘　　要：为了降低催化裂化汽油的硫含量,中国石油大连石化公司在1.4 Mt/a 重油催化裂化装置上对 XH-DSP 催化裂化汽油强化脱硫钝化剂进行工业应用试验。结果表明,XH-DSP 催化裂化汽油强化脱硫钝化剂具有优异的脱硫功能,催化裂化汽油中硫的脱除率(以硫传递系数计箅)随加剂量的增大而升高,当加剂量为400 μg/g 时,脱硫率可达75%;加剂量降至130μg/g 时,脱硫率为35%以上;平均加剂量为200μg/g 时,脱硫率为49.39%。另外,XH-DSP 强化脱硫钝化剂还具有良好的金属钝化功能,使用该剂后干气中的氢/甲烷体积比降低了23%。XH-DSP desulfurization and passivation agent was developed by the Shijiazhuang Star-Fire Scientific Testing Factory. It possessed the function of reducing the sulfur content of FCC naphtha and metal passivation simultaneously. In order to reduce the sulfur content of FCC naphtha,an industrial application of XH-DSP agent was carried out in PetroChina Dalian Petrochemical Company. The trial results showed that the sulfur compounds in FCC naphtha could be effectively removed, and with the increase of agent dosage the sulfur removal rate （calculated on sulfur transfer coefficient） increased. When the agent dosage was 400 μg/g, 200 μg/g and 130 μg/g, the sulfur removal rate was 75% ,49.39% and over 35% ,respectively. The ratio of hydrogen to methane dropped from 1.61 to 1.24 （a reduction of 23%）,indicating that said agent exhibited good metal passivation function as well.
