低温法费-托合成油加氢提质CFH~L技术开发及工业应用

介绍了中国石化石油化工科学研究院开发的低温法费-托合成油加氢提质CFH~L技术及工业应用情况,考察了操作条件对异构加氢裂化反应效果的影响。结果表明,反应温度、氢分压、体积空速对异构加氢裂化反应效果影响显著,氢油体积比影响较小。CFH~L技术工业应用结果表明,稳定加氢柴油馏分十六烷值为81,凝点小于-20℃;异构加氢裂化柴油馏分选择性为82.2%,异构裂化柴油馏分十六烷值为76,凝点为-53℃。

CFHL TECHNOLOGY FOR LOW TEMPERATURE F-T SYNTHETIC OIL HYDROUPGRADING AND ITS INDUSTRIAL APPLICATION

This paper introduced the RIPP`s low temperature F-T synthetic oil hydro-upgrading CFHL technology and its commercialization. The operating conditions on the effect of iso-hydrocracking reactions were explored. The results show that temperature, hydrogen pressure and space velocity significantly influence the iso-hydrocracking reaction, while the effect of H2/oil ratio is much less. The industrial application of CFHL shows that the cetane number of the hydrotreated diesel is 81 and the freezing point is below -20 ℃. The selectivity of iso-hydrocracking diesel exceeds 82.2%, while the cetane number of iso-hydrocracking diesel is 76 with a freezing point below -53 ℃.
