Abstract:

The Fischer-Tropsch synthesis (FTS) product contains various high value-added oxygenates. Lower carbon number oxygenates dissolve in the synthetic water, leading to the characters of strong acidity, high corrosion, pungent odor and difficult to be treated by bioprocess directly. Herein, realizing the targeted resources utilization according to the actual composition of FTS synthetic water is necessary. Only in this way can the economic and environmental benefits be maximized. With the development of indirect coal liquefaction industry, FTS synthetic water treatment technology has attracted increasing attentions from researchers. This article analyzed the compositional properties of FTS synthetic waters produced by different FTS technologies. Extraction and separation technologies for high value-added oxygenates that consists of oil separation, acid separation, and alcohol separation are reviewed. The technical advances in FTS synthetic water quality upgrading are also introduced. Also, the application and implementation performances of industrialized FTS synthetic water treatment technologies both domestic and overseas are summarized. At last, the future development direction of FTS synthetic water treatment including the improvement of high-efficiency integrated technologies, the expandable of the feedstock range, the reduction of energy consumption, as well as the reduction of the usage of various additives are outlooked.

Key words: Fisher-Tropsch synthesis, separation, recovery, upgrading, economics

摘要:

费托合成产物中含多种高附加值含氧组分。部分较低碳数含氧化合物溶解于合成水中,使其具有酸性强、腐蚀性强、刺激性气味、直接生物处理难度大等特点。根据实际组成有针对性地进行资源化利用才能实现经济和环境效益最大化。随着煤间接液化产业发展,费托合成产物中含氧组分资源化利用技术逐渐被更多研究者关注。本文分析了不同费托工艺产生的费托合成水相组成特点,综述了以油分离、酸分离、醇类等分离为步骤的高附加值含氧组分提取分离技术的最新进展,介绍了以高级氧化法、厌氧法等为代表的适用于费托合成废水提质的最新技术研究情况。最后总结了国内外成功工业化的费托合成水相产物处理技术应用情况及实施效果,提出了费托合成产物中含氧组分资源化利用技术的未来发展方向。
