【 摘 要 】

The effects of precursor, support and calcination procedure on the physical and chemical properties of supported cobalt catalysts have been investigated. A multiple characterisation approach of thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction and transmission electron microscopy was employed in order to gain understanding into the calcination and reduction processes. In addition, the catalysts were screened on a purpose built fixed bed reactor, under industrially relevant conditions, to determine effect of catalyst preparation on Fischer-Tropsch activity.
