摘要
针对页岩油柴油色度及氧化安定性差的问题,采用自制的复合脱氮剂进行脱氮处理,在络合剂质量分数为3%,络合反应时间为3.0min,络合反应温度为50℃,助剂加入量为1:1,静置时间为20.0min的条件下,碱氮脱除率可达到95.17%,精制油色度得到改善。脱氮页岩油柴油采用醇和添加剂进一步精制,在室温,剂油体积比为1:2,添加剂质量分数为0.2%的条件下,精制油色度和氧化安定性等指标均符合0^#柴油的标准要求,总收率可达80%以上。
In order to improve color and oxidation stability of diesel distillate from Fushun shale oil, pre-treatment of denitrification is done by using self-developed composite denitrogenation agent. Removal rate of basic nitride is up to 95.17% and the appearance color is improved under the following conditions :0.03 volume ratio of complex agent to oil, 3.0 minutes of reaction time,50℃ of reaction temperature, 1:1 volume ratio of the complex agent to assistant, and 20. 0 minutes of settlement time, Further refining on denitrified diesel distillate is carried out with alcohol as additive. At room temperature,with 1:2 volume ratio of solvent and oil, and 0. 2% of alcohol, the color and oxidation stability of refined diesel oil can meet quality standard requirements of 0^# diesel oil. The total yield of refined shale oil diesel distillate obtained from the combined process can reach up to 80%.
