稀土元素对铁-钾系乙苯脱氢催化的促进作用

The Role of Rare Earths in Fe-K Ethylbenzene Dehydrogenation Catalyst

采用催化剂性能参数的测定和X-射线衍射方法,对添加不同稀土元素化合物的Fe-K体系乙苯脱氢催化剂进行研究,结果表明Ce及Ce、La、Pr、Nd、Sm组合稀土元素化合物的添加有利于提高催化剂的活性和稳定性。

The role of rare earths in Fe-K ethylbenzene dehydrogenation catalyst was studied by catalytic properties valuation and XRD. The experiment result showed that rare earths Ce、La、Pr、Nd、Sm in dehydrogenation catalyst can enhance catalytic activity and stability of the catalyst.
