The interaction of carbon monoxide, hydrogen and ethylene (as intermediate and end product of the synthesis) with the contact was investigated under conditions approaching those of the true Fischer-Tropsch synthesis (temperatures up to 350 exp 0 C, pressures to 40 bar) and with a hydrogen-reduced mixture of iron and manganese oxide as model catalyst. Adsorption behaviour and adsorption states on the surface of the catalysts were investigated regarding single components as well as their mixtures. The kinetics of the adsorption or desorption were set up under different conditions, amongst these the pretreatment or precharging of the catalyst materials. Knowledge was also gained on the behaviour of the oxides and their mixtures when reducing with hydrogen (initial temperature, degree of reduction) and the effects of reduction and adsorption on the catalyst structure.
