正十二烷在Pt/ZSM-22和Pt/ZSM-23上的加氢异构反应性能
Hydroisomerization performance of n-dodecane on Pt/ZSM-22 and Pt/ZSM-23 catalysts
摘要
Abstract
ZSM-22 and ZSM-23 zeolites were synthesized via conventional hydrothermal methods.Then,two kinds of catalysts contained aforementioned molecular sieves were prepared respectively.The typical structure and acidity of molecular sieves and catalysts were characterized by using XRD,SEM,NH3-TPD and Py-IR.Then the hydroisomerization performance of these catalysts was studied in a continuous down-flow fixed bed,a stainless steel tubular reactor,where n-dodecane was chosen as the probe molecule.The reaction results indicated that the activity of the catalysts mainly depended on their acid quantity,acid intensity and acid distribution.ZSM-22 zeolite based catalyst with the relative higher amount of weak and mild acid sites exhibited better hydroisomerization selectivity than ZSM-23 zeolite based catalyst.关键词
