Abstract

The light alkenes formation capacity and the interaction of Mn with Fe and Fe-Co of Fischer-Tropsch catalysts have been studied. The samples were characterized by X-ray diffraction and temperature-programmed reduction. It was found that Fe-Co-Mn has a better catalytic stability than the Fe-Mn catalyst. It is proposed that iron particle size and its interaction with oxide and carbide phases produced during the catalytic reaction are mainly responsible for the high activity and light alkene selectivity.
