[求助] 校对一段摘要（炼油专业）

摘要：以大庆焦化柴油为原料，进行了焦化柴油络合脱氮剂的研究。考察了剂油比、反应温度、反应时间、沉降时间等工艺条件对脱氮效果的影响，确定了最佳脱氮工艺条件。利用络合脱氮—加氢精制组合工艺，在温度360 ℃，压力6.0 MPa，空速1.5 h-1，氢油比800:1及相同的加氢精制催化剂的条件下，以焦化柴油及其脱氮油为原料进行了对比评价，评价结果表明，脱氮油与未脱氮油相比，芳烃含量降低了6.9%，氮含量降低了31.5个单位，十六烷值提高了7.7个单位。因此，采用络合脱氮剂，在焦柴进行加氢精制前，先脱除其中的氮化物，可有效脱除芳烃，提高十六烷值，生产低硫、低芳、高十六烷值的清洁柴油。
关键词：焦化柴油；络合脱氮；加氢精制


Abstract：The complex denitrogenation agent of coker diesel was studied by using Daqing coker diesel as feedstock. The optimum denitrogenation condition was determined by investigating the effect of reagent/oil ratio, reaction temperature, reaction time and sedimentation time on the removal of nitrogen. Comparative evaluation was carried out using coker diesel and removal oil as feedstock with complex denitrogenation-hydrofining combining process under the same condition of 360℃, 6.0MPa, LHSV of 1.5h-1, H2/oil of 800:1 and hydrogenation catalyst. The evaluation results show that compared to coker diesel, the aromatic content and nitrogen content of denitrogen oil is 6.9% and 31.5 units lower respectively, cetane number increased by 7.7 units. Therefore, the removal of nitrogen before hydrofining by using complex agent can effectively remove aromatics, improve the cetane number, produce clean diesel with low sulfur, low aromatic and high cetane number.
Keyword: coker diesel; complex denitrogenation; hydrofining

第一句：以大庆焦化柴油为原料，进行了焦化柴油络合脱氮剂的研究。

究竟作了什么研究了？如果能补充这一点，会好一点。纵观整篇摘要，略改如下：

The performance and working conditions of complex denitrogenation agent for coker diesel were studied by using Daqing coker diesel as feedstock.

For the second sentence, the phrase "The optimum denitrogenation condition was" could be changed to "The optimum denitrogenation conditions were" as there are more than "one" condition to be adjusted.

For the 4th sentence, the phrase "the aromatic content and nitrogen content of denitrogen oil is 6.9% and 31.5 units lower respectively" could be changed to "the aromatic content and nitrogen content of denitrogen oil are 6.9% and 31.5 units lower, respectively."

The final sentence is restructured as below:

因此，采用络合脱氮剂，在焦柴进行加氢精制前，先脱除其中的氮化物，可有效脱除芳烃，提高十六烷值，生产低硫、低芳、高十六烷值的清洁柴油。

Therefore, by utilizing complex denitrogenation agent before hydrofining, it can effectively remove nitrogen compounds and aromatics (from the xxx), and increase cetane number, leading to the production of a clean diesel with low sulfur, low aromatic and high cetane number.
