Alumino-mesostructured Ni catalysts for the direct conversion of ethene to propene

In this work, the direct conversion of ethene to propene on Ni/MCM-41 and Ni/AlMCM-41 was studied. The Ni/AlMCM-41 with a Si/Al ratio of 60 revealed the highest conversion of ethene and the highest yield of propene. The combined effect between Ni state and the surface acidity of the catalyst is the responsible of the differences in the catalytic activity.75
