摘要：

The relative reactivities of the lower alkanes in hydrogenolysis on a Pt/Al2O3 catalyst depend on the H-2 pressure used, as do those of a Ru/AL(2)O(3) catalyst, pretreated in various ways, for propane hydrogenolysis. Apparent activation energies also vary with H-2 pressure. No single rate measurement adequately represents "catalytic activity", which is properly defined as the rate constant for the slow step.
