摘要
The influence of potassium on the activity and selectivity of titania-supported nickel-iron catalysts in Fischer-Tropsch synthesis has been studied. Small amounts of potassium increase the selectivity towards higher hydrocarbons, but decrease the CO conversion. The effects on the selectivity and the conversion are due to the presence of potassium on the surface of the nickel-iron alloy, which affects the adsorption and dissociation of CO and decreases the amount of active sites.
