Characterization and reactivity in toluene reforming of a Fe/olivine catalyst designed for gas cleanup in biomass gasification
2010
Abstract
To improve the gas production and quality of biomass steam gasification by tar reforming, an iron/olivine catalyst was designed for a use in fluidized bed gasifier. Various characterization techniques such as X-ray diffraction (XRD).
Mossbauer spectroscopy, Scanning Electron Microscopy combined with Energy Dispersive X-ray (SEM/EDX), X-ray Photoelectron Spectroscopy (XPS) and Temperature Programmed Reduction (TPR) were performed for detailed physicochemical characterization of Fe/olivine catalyst. Catalytic reforming of toluene as tar model compound was investigated.
Characterizations performed after tests indicate that a high percentage of iron in its metallic form is maintained leading to C-C and C-H bonds break.
