Iron has been incorporated into several zeolites with adsorption, ion-exchange, and anionic complexation procedures. These samples have been reduced in flowing hydrogen at temperatures between 300 and 500 °C. Particle size measurements using X-ray powder diffraction and electron microscopy techniques reveal that all of the iron phases of the reduced samples are between 50 and 150 Å. Changes in the catalysts due to their interactions with 10% CO H 2 at temperatures ranging from 260 to 400 °C were determined by Mössbauer spectroscopy using an in situ cell. Catalytic activity was monitored by a gas chromatograph and quantitative analysis of the product distribution was done in a separate differential reactor which was interfaced to a mass spectrometer. Alloy formation was not observed.
