Characterization of vanadia catalysts on structured micro-fibrous glass supports for selective oxidation of hydrogen sulfide

Characteristics of Carbon-Based Catalysts for the Selective Catalytic Oxidation of Hydrogen Sulfide

The development of low cost, highly efficient, desulfurization technology with integrated sulfur recovery remains a principle barrier issue for integrated gasification combined cycle power generation plants. For coal-derived synthesis gases with low sulfur content, direct air injection can be utilized to selectively oxidize the hydrogen sulfide present into elemental sulfur via the reaction H2S...

Selective Catalytic Oxidation of Hydrogen Sulfide from Syngas

Synthesis and Characterization of Nanostructured CuO/CeO2 Catalysts via Ultrasound Assisted Techniques used for Selective Oxidation of CO

Synthesis of structured filamentous zeolite materials via ZSM-5 coatings of glass fibrous supports

Structured filamentous zeolitic materials were synthesized by ZSM-5 coatings deposited on the glass fibrous supports. A homogeneous coverage of the support filaments was obtained via the synthesis of MFI crystals in fluoride-containing media at neutral pH ∼7. These materials combine the open macrostructure of woven filamentous fabrics with well-defined microstructure of ZSM-5 crystals. The samp...

Effect of liquid surface area on hydrogen sulfide oxidation during micro-aeration in dairy manure digesters

Although there are a variety of commercially available biological and chemical treatments for removal of hydrogen sulfide (H2S) from biogas, managing biogas H2S remains a significant challenge for agricultural digesters where labor and operational funds are very limited compared to municipal and industrial digesters. The objectives of this study were to evaluate headspace aeration for reducing ...
