【摘要】：為了推動煤基液體油分離技術(shù)的發(fā)展,實(shí)現(xiàn)油品中各組分利用價值的最大化,論述了煤基液體油的分離方法。煤基液體油的分離研究主要分為兩個方向:某一特定組分的分離和族組分的分離。某一特定組分的分離包括酚類化合物、雜環(huán)化合物和芳烴的分離,采用的方法主要有堿洗法、溶劑萃取、沉淀法、絡(luò)合法、液相色譜法、液膜萃取、超臨界萃取、低共熔法和離子液體萃取。族組分分離方法主要有溶劑萃取、超臨界萃取、柱色譜法和高效液相色譜法。每種分離方法各有優(yōu)缺點(diǎn)。按分離劑和分離目標(biāo)物之間的作用機(jī)制可歸結(jié)為4種分離原理:發(fā)生化學(xué)反應(yīng)生成第3種物質(zhì)、改變?nèi)芙舛�、利用吸附能力的差異和形成氫鍵及共軛作用。最后,針對煤基液體油分離中存在的問題,提出了研究方向與建議。
[Abstract]:In order to promote the development of coal based liquid oil separation technology and maximize the utilization value of components in oil products, the separation method of coal based liquid oil is discussed. The separation of coal based liquid oil is mainly divided into two directions: separation of certain components and separation of family components. The separation of compounds and aromatics mainly include alkali washing, solvent extraction, precipitation, collaterals, liquid chromatography, liquid membrane extraction, supercritical fluid extraction, low eutectic extraction and ionic liquid extraction. The methods of separation of group components mainly include solvent extraction, supercritical extraction, column chromatography and high performance liquid chromatography. Each separation method has the advantages of each method. The mechanism of action between the separation agent and the separation target can be attributed to 4 kinds of separation principles: the chemical reaction produces third substances, changes the solubility, uses the difference of adsorption capacity and forms the hydrogen bond and conjugation. Finally, the research direction and suggestion are put forward in view of the problems in the separation of coal based liquid oil.
