摘要

Refineries produce large amounts of H2S, which can be decomposed in the well-known Claus process to turn into sulfur and water. Due to the expensive chemical process and additional serious environmental issues, it causes, this approach is not commercially viable. Therefore, herein we have shown how to degrade toxic H2S using phocatalysis, a green, non-conventional energy source that is also environmentally friendly. In this research, laboratory experiments were conducted on a sample of diethanolamine solution (DEA) loaded with H2S from gas associated with oil at “the Swedish Gas Plant” in Syria. We have investigated the use of nanostructured CuO/ZnO/ZnFe2O4 photocatalyst for the degradation of H2S. The microstructure of the newly prepared CuO/ZnO/ ZnFe2O4 was examined using X-ray diffraction (XRD), Energy-Dispersive X-ray Spectroscopy (EDX or EDS), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The effect of pH and catalyst dosage was investigated on the photocatalyst performance.
