柴油加氢改质降凝技术的开发及工业应用

为了改善柴油的低温流动性能同时提高十六烷值,中国石化石油化工科研究院开发了加氢改质降凝技术及其RHC-130加氢改质降凝催化剂。研究结果表明,RHC-130催化剂对直馏柴油、催化裂化柴油、焦化汽柴油及其混合油具有良好的适应性,可在缓和的反应条件下生产不同牌号的满足国V排放标准的低凝柴油,具有凝点降低幅度大、十六烷值提高性能好、柴油收率高等优点。工业应用结果表明,通过调整反应温度可以灵活生产-35号、-20号、-10号低凝柴油。

DEVELOPMENT AND INDUSTRIAL APPLICATION OF DIESEL HYDROUPGRADING PROCESS FOR IMPROVING COLD FLOW PROPERTIES

In order to improve the cold flow property and cetane number of diesel, a new diesel hydroupgrading process and RHC-130 catalyst were developed by SINONEC Research Institute of Petroleum Processing. The results show that different types of low solidification point diesels which meet the national V diesel standard under mild conditions can be produced, indicating a good adaptability of RHC-130 catalyst to straight run gas oil, LCO, coker gas oil and their mixed oils. The large improvements in solidification point, cetane number, and yield of diesel can be obtained. The industrial application demonstrates that the－35#, －20# or －10# diesels can be produced by adjusting reaction temperature.
