【摘要】 稠环芳烃物种含有大量的芳烃资源,由于苯环间的共轭效应,难以将其直接转化。随着原油芳烃含量的逐年增高,在工业规模如何有效地处理稠环芳烃备受关注。对稠环芳烃的加氢裂化和催化裂化反应机理进行总结对比,并通过介绍裂化催化剂的研究进展为稠环芳烃的催化裂化拓展新思路。更多还原

【Abstract】 Polycyclic aromatic hydrocarbons contain large amounts of aromatic hydrocarbons,which are difficult to convert directly due to the conjugated effect of benzene rings. In recent years,the content of aromatics in crude oil has been increasing year by year. How to crack polycyclic aromatic hydrocarbons on an industrial scale has attracted much more attention. The mechanism of hydrocracking and catalytic cracking of polycyclic aromatic hydrocarbons have been summarized and compared. By introducing the progress of corresponding catalysts,new ideas might be developed for the catalytic cracking of polycyclic aromatic hydrocarbons.更多还原
