Vibrational Analysis of an Industrial Fe-Based Fischer-Tropsch Catalyst Employing Inelastic Neutron Scattering

Inelastic neutron scattering (INS) has been used to obtain the vibrational spectrum of a technical‐grade iron‐based Fischer–Tropsch catalyst that has been taken from an industrial large‐scale unit operation. Whereas previous reports on iron Fischer–Tropsch catalysts highlight the presence of retaine...

Description
Summary:Inelastic neutron scattering (INS) has been used to obtain the vibrational spectrum of a technical‐grade iron‐based Fischer–Tropsch catalyst that has been taken from an industrial large‐scale unit operation. Whereas previous reports on iron Fischer–Tropsch catalysts highlight the presence of retained carbonaceous species, the INS spectra reveal the additional presence of partially hydrogenated aromatic molecules (see picture).
