Abstract
The application relates to a process for the removal of hydrogen sulfide from a gas stream by catalytic direct oxidation without employing the combustion step of a Claus process. The process is particularly suitable for desulfurization of gas streams that contain hydrogen and allows sulfur recovery efficiency of better than 99%.
