Silica is well known as a support for cobalt supported Fischer-Tropsch catalysts. Silica has a high surface area with an amorphous structure that promotes dispersion of the active cobalt phase over the support surface. This dispersion is vital in terms of catalyst performance and derives from the strength of interaction between the cobalt and the support. However, the stronger the metal support interaction, the greater is the loss of active cobalt through formation of cobalt support species that are hard to reduce. Consequently ZnO and MnO were evaluated in comparison to Si02 as supports for cobalt supported Fischer-Tropsch catalysts. The aim of the study was to characterise the interaction between cobalt and the three supports (Si02, ZnO and MnO) in terms of the cobalt reducibility as visualised using TPR, exposed cobalt surface area and cobalt dispersion as evaluated using hydrogen chemisorption, and catalytic performance under Fischer-Tropsch synthesis conditions. 2016-03-17T12:42:28Z 2016-03-17T12:42:28Z 1999 Master Thesis Masters MSc (Eng) http://hdl.handle.net/11427/17953 eng application/pdf Department of Chemical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
