摘要
本文制备了采用不同方法制备的Ru/C纳米催化剂,并考察了它们对大豆油加氢反应的催化活性。结果显示乙二醇还原的催化剂比表面积大,颗粒分散,所以催化活性最高,对顺式产物的选择性也最高。其他两种催化剂比表面积较低,而且部分颗粒出现密集和团聚现象,受到空间位阻效应影响较大,所以它们的活性和顺式产物选择性都比较低。
In this thesis,Ru/C catalysts were prepared by different methods,and the activity and selectivity of these catalysts for hydrogenation of soybean oil were examined.The catalyst reduced by EG,which was well dispersed and had the largest metal surface area,showed the highest activity.The other two catalysts had lower activity and particle is concertrated because the lower specific surface area and higher steric hindrance.
