Synthesis of light alkenes on manganese promoted. (González Cortés, Sergio Luis; Rodulfo Baechler, Serbia M. A.; Oliveros Bastidas, Alberto; Orozco, José; Fontal, Bernardo; Mora, Asiloé J.; Delgado, Gerzon) 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.
