煤直接液化油加氢提质RCHU技术的工业应用

介绍中国石化石油化工科学研究院开发的煤直接液化油加氢提质RCHU技术在全球首套百万吨级煤直接液化油加氢提质装置的工业应用及标定情况。结果表明:装置石脑油产品硫质量分数低于0.5 μg/g,芳烃潜含量达68%左右;柴油产品密度(20 ℃)为0.842~0.855 g/cm^3,硫质量分数低于0.5 μg/g,产品质量达到设计要求;催化剂经过两次再生,累计运行近9年后仍保持较好的反应性能,稳定性好,取得良好的应用效果。

INDUSTRIAL APPLICATION OF HYDRO-UPGRADING TECHNOLOGY RCHU FOR THE OIL FROM DIRECT COAL LIQUEFACTION

The hydro-upgrading technology RCHU developed by SINOPEC Research Institute of Petroleum Processing was applied to the world’s first set of coal liquefaction unit with a capacity of 1.0 Mt/a in China Shenhua Coal to Liquid and Chemical Ordos Coal Liquefaction Company. The sulfur content of naphtha product was lower than 0.5 μg/g and the potential aromatic content was around 68%. For the diesel product, the density（20℃）was in the range of 0.84~0.85 g/cm3 and the sulfur content was lower than 0.5 μg/g. The qualities of the products met the requirements. The unit operated for nearly 9 years with twice regenerations of the catalysts. The long-period of operation indicates that the RCHU technology has a great performance in operation stability.
