Promoting effect of oxygen for hydrogenation of butadiene over Ni/sub 2/P catalyst
The influence of oxygen on the rate of hydrogenation of butadiene over Ni/sub 2/P catalyst has been investigated in the view of the results reported previously (Nozaki, F. and Adachi, R., J. Catal. 40, 166, 1975). When a partial pressure of several mm Hg of oxygen was added into the reactant gas mixture, the hydrogenation activity increased remarkably in a complicated manner following an induction period. In addition, the oxygen resulted in a significant increase in the amount of adsorption of hydrogen. The temperature-programmed desorption spectrum of oxygen given the definitive evidence that there are at least two different surface species of oxygen. Furthermore, with the aid of the information obtained from measurements of adsorption isotherms, infrared spectra of the catalyst, and analysis of the deuterium distribution of the products formed in the reaction of butadiene with D/sub 2/, a plausible mechanism for the promoting effect of oxygen on hydrogenation has been proposed. 10 figures, 1 table.
