Conception and Development of a Photocatalytic Reactor for H2s Degradation

For the development of a photocatalytic reactor on an industrial scale it was evaluated the degradation of hydrogen sulphide (H2S) from tests with different coatings based on TiO2. The surfaces formed with these coatings were structural and morphologically characterized by scanning electron microscopy with energy dispersive X-ray (SEM-EDX) and X-ray diffraction (XRD) analysis. The flow rate, inlet concentration of H2S, activation and deactivation times (saturation) were evaluated as performance parameters of the degradation reaction. Conversion rates were studied for different residence times (RT), with a conversion of up to 95 % for RT = 30 s.
