摘要
同催化加氢脱硫技术相比,非加氢脱硫技术是在常压和较低的温度下进行操作的,具有投资小、操作安全和成本较低等优势,进而越来越受到国内外研究者的高度重视。针对国内外目前开展的液体碳氢化合物采用的非加氢脱硫技术的特点,本文重点对酸碱精制、吸附法、催化法、萃取法、氧化法、微生物法、辐射法和离子液体法等非加氢脱硫技术的原理和工艺进行了分析比较,指出了每种脱硫技术存在的优缺点,并对今后脱硫技术的发展提供指导。最后认为脱硫工艺的发展前景为现有各脱硫工艺的联合使用。
Compared with the catalytic hydrogenation desulfurization technology,non-hydrogenation desulfurization technology can be used under atmospheric pressure and at a low temperature with the advantages of small investment,safe operation and lower cost.The principles and techniques of non-hydrogenation desulfurization technology,including acid-base purification,adsorption,catalysis,extraction,oxidation,microbiological method,radiation and other ionic liquid method were compared,and their respective advantages and disadvantages were discussed to provide guidance for the development of desulfurization technology.The prospect of desulfurization process is a combination of the above desulfurization processes.
