文章摘要
assembled to catalyst for the C8 aromatics isomerization process. The catalytic properties were tuned
through careful modification of the acidity of EU-1 zeolites and metal-doping of the catalyst. It was
shown that EU-1 was an excellent candidate for the C8 aromatics isomerization process due to its unique
structure. In addition, steam treatment of EU-1 at 450-500 °C could optimize the acidic properties of
the catalyst, hence enhance its catalytic performance. The effect of the amount of Pt on ethylbenzene
conversion was studied and the optimum amount was determined to be about 0.3-0.4 wt%. It was
confirmed that EU-1 zeolite prepared via a quasi-solid state approach and then dealuminated by steam
treatment had better activity and selectivity than conventional mordenite (MOR) zeolite and could be an
excellent candidate for C8 aromatics isomerization.
