Iron oxide catalyst at the modified glass fiber support for selective oxidation of H<sub>2</sub>S

Abstract

The novel iron-oxide based glass-fiber catalysts (GFC) for the H₂S selective oxidation uses the support in form of the glass microfibrous fabric, premodified by external layer of secondary porous SiO₂ support. The specific activity of FeOx-SiO₂/GFC catalyst per unit mass of active component exceeds that of the similar conventional Fe₂O₃/Al₂O₃ catalyst by more than an order of magnitude due to the more dispersed state of active component in the GFC (1–2 nm compared to 15–30 nm in conventional catalyst). The proposed GFC also looks advantageous in terms of mass transfer efficiency and easy scale-up.
