Abstract
The promotional effect of potassium was studied on catalytic behavior of iron in CO2 hydrogenation. A higher product selectivity toward light olefins and long-chain hydrocarbons was obtained on promoted catalyst than on unpromoted catalyst. This can be attributed to the enhancement of carburization on iron catalyst by potassium, as evidenced by Mössbauer spectroscopy and temperature-programmed decarburization.Keywords
