Reaction of CO/H, over an Iron/Carbon Catalyst Li-Min Tau and Carroll 0. Bennett* Department of Chemical Engineering, University of Connecticut, Storrs, Connecticut 06268 (Received: January 30, 1986)
In the present work the CO/H2 reaction is studied over 10% Fe/C and compared with previous studies over 10% Fe/A1203 and 10% Fe/Ti02. A medium area carbon black (BET 400 m2/g) is selected as support. Characterization by transmission electron microscopy and X-ray diffraction indicates that there is a broad distribution of particle size for the reduced catalyst. Mossbauer effect spectroscopy shows that the metallic iron present has two sets of hyperfine fields. The field at 334 kOe is assigned iron particles of diameter >10 nm, and the field at 309 kOe is assigned to particles of diameter
