Abstract

AbstractSeveral potassium promoted catalysts have been prepared by adsorption of K4[Fe(CN)6], K3[Co(CN)6] and K2[Ni(CN)4] on acid‐modified γ‐alumina. Subsequent H2 treatment with or without previous calcination step has been carried out in order to study the influence of the sample pretreatment on the catalytic behavior in the CO hydrogenation reaction. Some characteristics of the catalysts have been studied after reaction by means of Mössbauer and X‐ray photoelectron spectroscopic techniques. The catalytic properties for CO hydrogenation were found to be affected by the pretreatment conditions, especially for iron catalysts. A high selectivity to olefins and a low production of long chain hydrocarbons were obtained in the reaction over non‐calcined iron catalysts. For iron catalysts noticeable differences in the Anderson‐Schulz‐Flory distribution of hydrocarbons were induced by the catalyst pretreatment. Such differences induced by catalyst pretreatments were, however, smaller for cobalt‐containing catalysts. In the CO hydrogenation on potassium‐promoted nickel catalysts a high production of long chain hydrocarbons and a high selectivity to olefins were found when compared to the unpromoted nickel‐catalysts.
