Correlation of Distribution of Activation Energy of Hydrogen Desorption with Catalytic Activity in Ethane Hydrogenolysis by Silica-Supported Nickel Catalysts.

Abstract

In this work, we attempt to correlate the distribution of activation energy of hydrogen desorption for supported nickel catalysts with activity in a structure-sensitive reaction of ethane hydrogenolysis. It is known that ethane hydrogenolysis activity is not simply correlated by the size of metal particles of catalysts (Sinfelt, 1970; Ponec and Bond, 1996). From a practical point of view, a good parameter for correlating and predicting the activities of industrial catalysts is needed. We have examined the possibility of the activation energy distribution for this purpose.
