Abstract: A preparation method of Fe3Cultrafine particle catalyst,from highly dispersed amorphous Fe powder and free carbon by laser pyrolysis technique,was investigated.The catalytical reactive species,α-Fe,and iron carbonide catalyst for F-T synthesis were obtained directly.The catalyst obtained under different experimental conditions was characterized by XRD,electronic diffraction and TEM techniques.The influences of preparation condition on the crystalline grain size,crystal shape of the catalyst obtained and the component of iron carbonide in the catalyst,are also disscused.

Key words: F-T synthesis, Ultrafine particle catalyst, Iron carbonide
