Abstract
The relative reactivity of the adsorbed species during a catalytic methanol synthesis reaction on a ternary-component catalyst was investigated. Abrupt changes in the ambient pressure of a component in the gas phase, at a nearly equilibrium condition, were correlated with the corresponding changes in the amounts of the adsorption and in the total ambient pressure. The data collected from such dynamical treatments indicate that the species adsorbed on the catalyst surface, in a nearly equilibrated system of the simultaneous adsorption of hydrogen and carbon monoxide, is mostly the surface intermediate complex formed from both of them. Furthermore, the results obtained suggest an order for the reaction speed of each elementary step in the methanol synthesis reaction.
