FE-CO TIO2 BIMETALLIC CATALYSTS FOR THE FISCHER-TROPSCH REACTION .1. CHARACTERIZATION AND REACTOR STUDIES/

The effect of different iron loadings (0.1%; 1%; 5%; 10%) on a 10% Co/ TiO2 catalyst was studied by a range of surface and bulk characterizat ion techniques. The combination of techniques (B.E.T.; CO-chemisorptio n, desorption; DSC; XRD; XPS; TPR; TPD; SEM and Mossbauer Spectroscopy ) revealed that an intimate interaction occurs between the Fe and Co a toms when compared to the pure metal components. Catalyst preparation and reduction procedures influenced both the bulk and the surface prop erties. The characterization studies revealed that the TiO2 systems do not differ significantly from SiO2 and Al2O3 supported, or alloy syst ems, reported elsewhere in the literature.
