我国航空燃料精制工艺装备技术进展

我国每年生产 50 0多万 t航空燃料。随着炼油厂高硫、高酸值原油加工比例的不断提高 ,使航空燃料中腐蚀性有害物质的含量也随之增加 ,对飞机的供油系统和发动机燃烧系统产生严重的腐蚀与破坏 ,直接威胁到飞行的安全 ,因此 ,需要将它们从航空燃料中分离出去。为此 ,对目前我国航空燃料精制工艺装备技术进行了较全面的论述和深入的分析 ,结合中国的实际情况和国外发展趋势 。

Study on Laboratory Method for Refining of SR Diesel Fuel

The method for refining the straight-run diesel fuel was studied in laboratory scale in order to make the acid number of diesel fraction comply with the standard while removing the naphthenic acids contained in diesel without causing environmental pollution. After comparing the effect of refining using three solvents, the isopropyl alcohol-HOA was specified as the best solvent. Meanwhile, the relationship between the acid number of diesel fraction and the amount of solvent used and the relationship between the concentration of solvent and temperature and the stability of diesel in terms of its acid number were also investigated. Experimental results had shown that when the mass fraction of the HOA-IPA solvent was 20% at a dosage of 17 mL of the solvent and a temperature of 30℃, the acid number of the refined diesel fraction was 0.015 mg KOH/g with a good stability of acidity in the diesel fraction.
