Various metal oxides will be synthesised and analysed under process conditions to study deactivation mechanisms of the catalysts, surface species and HDO reactions mechanisms. Finally, the influence of water on isomerisation reactions of the products is studied.
Currently hydrodeoxygenation (HDO) of waste vegetable oils is performed using catalysts which are normally used for hydrodesulphurisation reactions. These catalysts, however, require sulphur to be present to function which adds to costs in refining. During this research, catalysts for the HDO of waste oils will be developed, where specific emphasis lies on finding and understanding catalysts resistant to water vapour at process conditions as well as performing these reactions without the presence of sulphur in neither catalyst nor feed. Various metal oxides will be synthesised and analysed under process conditions to study deactivation mechanisms of the catalysts, surface species and HDO reactions mechanisms and eventually influence of water on isomerisation of the products.
