英文摘要: A new propene production route from 1-butene metathesis has been developed on heterogeneous 10WO(3)/Al(2)O(3)-HY catalysts with different HY contents. It is found that the catalysts play bi-functionally first for the isomerization of I-butene to 2-butene and then for the cross-metathesis between 1-butene and 2-butene to propene and 2-pentene. The combination of HY zeolite and Al(2)O(3) is prerequisite for the production of propene. The propene yield keeps increasing with the HY content in the range of 10-70 wt%, where 10WO(3)/Al(2)O(3)-70HY exhibits the highest propene yield. The MS-H(2)-TPR and MS-O(2)-TPO characterizations indicate that the increase of HY content in the catalysts weakens the interaction between W species and supports, whereas enhance the probability of coking on the metal species and acid sites.
