Abstract

In this paper, we demonstrate that syngas (H₂/CO) can be produced from oil waste (H₂S/CO₂) forming SO₂ and S as secondary products at 600–800 °C in a flow reactor set-up. Numerous different metal sulfide catalysts have been tested for activity, with FeS and NiS appearing to be the most active. In both cases, the catalyst remains active after 120 hours online. X-ray diffraction confirmed that the catalyst remains under the form of the metal sulfide.
