Characterization of Spent Catalysts during Hydrodemetallization of Atmosphere Residue

Abstract:

The deactivation behavior of industrial hydrodemetallization catalysts was investigated in the presented work. The main objective of the study is to contribute to a better understanding of the nature of the coke and metal deposition on the used catalysts by applying chemical analysis and various advanced analytical techniques, such as X-ray diffraction analysis (XRD), thermal gravimetric analysis (TGA), transmission electron microscopy (TEM), and solid-state carbon-13 nuclear magnetic resonance spectroscopy (¹³C NMR). The results are discussed scientifically based on the physico–chemical properties of origin and used catalysts.
