Abstract

From in-situ Mössbauer spectra recorded at room temperature it is concluded that the support material (carbon or alumina) influences the degree of sulfidation of Fe and FeMo hydrotreating catalysts. For the latter a Fe-Mo-S phase is observed. By combining Mössbauer spectroscopy and ordinary ¿-ray spectroscopy the sulfur uptake by the catalyst has been studied.
