摘要: 选择性开环技术可以使芳烃转换成单环烷烃或链烷烃化合物,极大地提高了柴油的清洁度和十六烷值,该技术的核心是开发具有加氢和开环性能的双功能催化剂。本文综述了近年来国内外催化裂化(FCC)柴油芳烃选择性开环催化剂的研究进展,重点讨论了催化剂载体、活性金属及制备方法3个方面对加氢开环反应性能的影响。分析表明载体的酸性和孔道结构、负载活性金属的类型(包括非贵金属和贵金属)及不同的制备方法对催化性能有极大影响。最后对柴油芳烃选择性开环催化剂的研究提出了一些建议,指出今后研究的重点是开发具有适宜酸性和孔结构的新型载体及能够保持活性和稳定性的活性金属组分并加强该领域反应机理的研究。

Abstract: The technology of selective ring opening can make the aromatics into a single naphthene or alkane compounds and greatly enhance the cleanliness and cetane number of diesel fuel, and the core of this technology is to develop the bifunctional catalysts with abilities of both hydrogenation and ring opening performance. Recent advances in aromatic hydrocarbon selective ring opening catalyst for FCC diesel oil have been introduced. The effects of catalyst carrier, active metal and preparation method on hydrogenation ring opening reaction performance are discussed. Analysis indicates that the acid and structure of the carrier, the type of active metal and different preparation methods can all greatly influence the catalytic performance. Finally, we put forward some suggestions on the research of the selective ring opening catalyst. The focus of future research is to develop new carrier with the suitable acidity and pore structure and the active metal components, and strengthen researches of the reaction mechanism.

Key words: FCC diesel, hydrogenation, selectivity, catalyst, preparation method
