摘 要: | 国内某石化公司1.4 Mt/a喷气燃料加氢装置采用中国石化抚顺石油化工研究院开发的FH-40B催化剂。装置标定结果表明,采用FH-40B催化剂处理直馏喷气燃料(总硫质量分数为0.14%),在反应器入口压力1.75 MPa、反应器入口温度265℃、氢油体积比100、体积空速2.95h-1的条件下,产品的硫醇硫质量分数低于3μg/g,烟点为24.5mm,萘系烃体积分数为0.36%,冰点为-57.2℃,催化剂具有优异的脱硫醇硫性能,并能使喷气燃料产品的烟点稍有提高,所得喷气燃料产品质量满足3号喷气燃料国家标准(GB 6537—2006)的要求。装置运行结果表明,FH-40B催化剂失活速率为0.021℃/d,催化剂床层压力降变化趋势较平缓,催化剂具有良好的活性和稳定性,有利于工业装置的长周期运行。

COMMERCIAL APPLICATION OF FH-40B CATALYST FOR JET FUEL HYDROGENATION |
| |
Abstract: | FH-40B catalyst developed by SINOPEC Fushun Research Institute of Petroleum and Petrochemicals was commercially used in a 1.4 Mt/a jet fuel hydrogenation unit of a petrochemical refinery. The calibration results showed that the qualified No.3 jet fuel (in compliant with GB 26537—2006) can be produced from the feed with 0.14% μg/g sulfur. The jet fuel produced is characterized by the mass fraction of mercaptan sulfur of 3μg/g, smoking point of 24.5 mm, freezing point of -57.2℃ and the volume fraction of naphthalenes of 0.36% at reaction conditions of 265 ℃,1.75 MPa, hydrogen/oil volume ratio of 100 and LHSV of 2.95 h-1. The commercial results demonstrated that the catalyst FH-40B has a good activity and stability, the catalyst deactivation rate is 0.021 ℃/d, the pressure drop of the catalyst bed is smooth, which is favor of long-running for the unit. |
