Cleaning fuel

All crude oils contain between 0.1% and 2.5% of sulphur dependant on their source of origin. Upon combustion, the sulphur from these crude oils is converted into sulphur oxides – an air pollutant that can dissolve in rainwater creating acid rain which damages crops, forests and aquatic species.

Cobalt plays a vital role in catalysing the removal of sulphur from oil, contributing to a more sustainable society. Desulphurisation is the process by which sulphur is removed from oil. A significant use of cobalt globally is as part of catalysts in this desulphurisation process. The use of cobalt in desulphurisation reactions represents the highest tonnage of cobalt use in the catalyst sector.
