龙口页岩柴油络合萃取精制工艺研究

Research on Refining Process of Longkou Shale Diesel by Complexation Extraction

以龙口页岩油为原料,取其柴油馏分为研究对象,采用糠醛和FeCl3-甲醇溶液为络合萃取剂对龙口页岩柴油进行萃取络合研究。考察了糠醛及FeCl3-甲醇溶剂量对对页岩柴油色度和碱氮含量的影响。结果表明,络合萃取后龙口页岩柴油中碱性氮化物可得到有效的脱除。

Taking Longkou shale oil as raw material, diesel fraction as the research object, Longkou shale diesel was extracted by using furfural and FeCl3 - methanol solution as the complexation extraction agent. Effects of furfural amount and FeCl3 - methanol solvent amount on chromaticity and alkaline nitrogen content of shale diesel were investigated. The results show that basic nitrogen compounds in Longkou shale diesel can be effectively removed by complexation extraction.
