Abstract
The invention concerns a process for desulphurizing a feed comprising oxygen-containing compounds, hydrocarbon-containing compounds and organic sulphur-containing compounds, by capturing sulphur on a capture mass comprising iron oxides or zinc oxides and more than 20% by weight of zinc ferrite. The process is operated in the presence of hydrogen at a temperature in the range 200° C. to 400° C.
