- W2002241200 abstract "Abstract The catalytic activity of nickel in ethylene hydrogenation is shown to result quasi-completely from active sites created by the partial or entire simultaneous conversion into water of the oxygen traces carried by the reacting mixture. The ethylene hydrogenation and the water synthesis appear then to be coupled upon the catalyst surface, the former proceeding on the active centers generated by the latter. As the rate of disappearance of active centers increases with temperature whereas the total oxygen conversion is limited, a maximum occurs in the steady-state activity versus temperature. This scheme is proved by the disappearance of this optimum, with a considerable lowering of activity, following a drastic purification of the reacting mixture. The maximum and activity both reappear when the purification becomes less rigorous." @default.
