|
摘要
介绍了中国石化大连(抚顺)石油化工研究院焦化煤油馏分加氢生产液体石蜡原料工艺的试验研究结果及工业应用情况。中型试验结果表明,处理典型的焦化煤油馏分,在反应压力为5.5 MPa、平均反应温度为320℃、体积空速为1.5 h~(-1)、氢油体积比为400或反应压力为4.5 MPa、平均反应温度为320℃、体积空速为1.0 h~(-1)、氢油体积比为400的条件下,可以将其硫和碱性氮质量分数降低至1.0μg/g以下,满足液体石蜡原料的质量要求。工业应用结果表明,焦化煤油馏分加氢生产液体石蜡原料是完全可行的。该研究结果为缓解液体石蜡原料紧张,提高焦化馏分油的附加值提供了一条新的技术路线。
The coking kerosene distillate was hydrotreated to produce the feedstock for the liquid paraffin production by SINOPEC Dalian(Fushun) Research Institute of Petroleum Processing(FRIPP)and its industrial application was introduced.The pilot test results showed that when typical coking kerosene fractions were hydrotreated at 5.5 MPa,320 ℃,LHSV 1.5 h~(-1),the volume ratio of hydrogen/oil 400 or at 4.5 MPa,320 ℃,LHSV 1.0 h~(-1) and the volume ratio of hydrogen/oil 400,the content of sulfur and nitrogen in product can be reduced to less than 1.0 μg/g,which meets the quality requirements of liquid paraffin feedstock.The industrial application proved the feasibility of producing liquid paraffin feedstock by hydrogenation of coking kerosene distillate.It is concluded that the hydrogenation technology can provide a new technical route to supply liquid paraffin feedstock with increasing the added value of coking distillate oil.
