Residual oil hydrotreating catalyst rejuvenation by leaching of foulant metals: effect of metal leaching on catalyst characteristics and performance
The effects of metal leaching on catalyst characteristics are reported and discussed. Samples of spent catalyst and chemically treated catalysts were characterized for surface area, porosity and chemical composition. The influence of chemical treatment on the distributuion of foulant metals (V and Ni) and the active metals (Co and Mo) within the catalyst pellet was examined by electron microphobe analysis.The samples were also tested for HDS activity recovery as a result of the rejuvenation process.
