C*change paraffin activation: Towards an integrated process for the functionalisation of alkanes to value-added products
My work is focussed on the valorisation of low-value hydrocarbons, including alkanes and alkenes. South Africa produces a large excess of these low-value feedstocks. These hydrocarbons are typically used as either cheap fuels or solvents due to their chemical inertness, prohibiting further derivatisation or chemical modification. The selective oxidation of such hydrocarbons to the much more valuable oxygenates (under mild conditions), is highly challenging. In particular, the selective oxidation of alkanes remains one of the great challenges in modern chemistry. In order to accomplish this, both enzymatic biocatalysis as well as traditional heterogeneous catalysis are employed. Of particular interest is the combination of such catalytic processes into a single tandem process that draws upon the advantages of both biocatalysis (green, mild conditions, highly selective) as well as chemocatalysis (well developed, high activity) and seeks to create a process greater than the sum of its parts. .
A further research interest includes the in-situ generation of environmentally benign oxidants such as H2O2. Such oxidants are often employed in the oxidation of hydrocarbon substrates by various catalysts. The in-situ generation of these oxidants from abundant and, more importantly, cheap starting materials such as air and H2 is highly advantageous from an economic perspective.
