摘要
分析了重整生成油中烯烃的分布状况及影响因素,概述了国内外重整芳烃中烯烃的脱除技术进展和催化剂的研究开发情况,提出了我国发展重整芳烃脱烯烃工艺和催化剂的研究思路。重整生成油中的烯烃主要以C6烯烃和C7烯烃为主,其含量与重整反应的苛刻度及催化剂类型有关,反应苛刻度越高,烯烃含量越高。开发能够替代工业白土、具有较高活性和稳定性、能多次再生的脱烯烃催化剂是未来的发展方向。
The present status and developing trend of processes and catalysts for removing olefins from reformate were introduced focusing on the evolvement of the processes and R 8- D of the catalysts in a few large petroehemical corporations worldwide. The distributions of olefins in reformate and factors affecting the formation of olefins were discussed, It was found that C6 and C7 olefins were the main olefins in reformate, and their contents increased with the reaction severity. Finally, suggestions for domestic research thinking in these aspects were proposed,sueh as developing catalyst having high activity and stability,can be regenerated for times to replace clay treatment substantially and so on.
