Introduction Supported rhenium oxide catalysts have a wide range of catalytic applications, such as olefin metathesis, hydrodesulfurization, hydrogenation and NH3-SCR. Hence, the practical importance of rhenium oxide catalysts has resulted in extensive investigation of the surface structure of supported rhenium oxide catalysts. The molecular structure of supported rhenium oxides has been mainly...
This study evaluates the recovery of heavy metals employing a spent catalyst from the hydrodesulfurization (HDS) of diesel, with no chemical, thermal or physical pretreatment, using the bacterial strain Acidithiobacillus thiooxidans FG-01. Direct and indirect bioleaching tests were carried out in Erlenmeyer flasks (500 mL). The influence of the pulp density and supplementation with elemental su...
