摘要：

Carbon monoxide hydrogenation has been studied on polycrystalline cobalt foils, using a combination of UHV studies and atmospheric pressure reactions at 525 and 575 K and the effects of different promoters (K and Mg) have been investigated. The selectivity towards methane was decreased due to both promoters. The main effect with potassium was,however, the suppression of carbon deposition at higher reaction temperatures.
