Preparation of model cobalt catalysts for Fischer-Tropsch synthesis using ultrasound preparation techniques

In order to study the oxidation behaviour of small cobalt crystallites during Fischer-Tropsch synthesis, it is necessary to prepare model catalysts with cobalt crystallites of which the size distributions can be adjusted. Here ultrasonication was used to decomposed a tricarbonyl precursor in n-decane to prepare small cobalt crystallites. The aim of this study was to vary the cobalt crystallite size distribution by adjusting the preparation conditions. Transmission Electron Microscopy (TEM) was used to measure the crystallites and to obtain the crystallite size distributions.
