Interaction of hydrogen and carbon monoxide on cobalt catalysts-Part II

Abstract

The simultaneous adsorption of CO and Hz from their 1:1 mixture on a cobalt Fischer-Tropsch catalyst has been studied by kinetic and quasi-static measurements in the temperature range 0-132°C. Mutual enhancements indicating interactive adsorption have been observed in both rates and amounts of adsorption. Breaks appear in the Elovich equation plots for the rates of adsorption of both gases from the mixture. The ratios of the post-break slopes of these plots check fairly closely with the H2/CO ratios in the mixed adsorbed phase found under quasi-static conditions. Both types of measurements indicate the formation of a surface compound of the composition H2C0 in the temperature interval 85-95°C. The kinetics of interaction of hydrogen with the composite adsorbate formed at various temperatures have also been studied.
