Pulse reactor studies of the activity of supported nickel catalysts in which 0-2.37% sodium was added to the support showed that the activity for cumene dealkylation decreased with increasing sodium content, ethane hydrogenolysis decreased with increasing sodium content above 0.44% and benzene hydrogenation decreased with successive pulses on the more acidic catalysts. Cyclopropane hydrogenation/hydrogenolysis on all catalysts produced methane and carbonaceous residue with the first pulse, followed by increasing activity for both hydrogenolysis and hydrogenation. Hydrogenation selectivity increased with increasing sodium content. A discussion of these results shows that the support acidity has no direct effect on the benzene, ethane, and cyclopropane reactions. Diagram, graphs, tables, and 36 references.
