摘要:

简述了国内外在柴油加氢脱芳烃反应动力学模型方面的最新研究进展。指出芳烃的存在会降低柴油的质量,也是对健康的威胁,降低柴油中的芳烃含量十分必要。提出催化加氢是降低柴油中芳烃含量的有效途径。介绍了芳烃加氢反应的动力学和热力学特点。详细叙述了柴油馏分加氢脱芳烃反应的简单集总模型和复杂集总模型。简单集总模型比较简洁实用,但在精确性上略有不足。复杂集总模型计算准确,但对于普通应用而言,复杂且费用不菲,这限制了它的应用。最后总结指出对于新开发的动力学模型,还需要在准确性上下功夫,同时尽可能降低模型开发和使用的成本。这对于模型的推广和应用有着重要的意义。

Abstract:

Due to the lower diesel qualityand harm to health of aromaticsit is necessary to reduce the content of aromatics in diesel. Hydrogenation is an effective way to reduce the content of aromatics in diesel. Thermodynamics and kinetics of hydrodraromatization are introduced. Simple lumping model and complex lumping model of diesel hydrodearomatization reaction are described. Simple lumping model is concise and practicalbut its accuracy is not satisfactory. Complex lumping model is accuratebut it is complicated and expensive for general applicationwhich limits its application. For kinetics modelaiming at higher accuracy is necessaryand lowering the cost of development and use are significant in its application.
