ABSTRACT

Catalysts are of great importance in catalytic processes. Key features of oil hydrotreating catalysts are highlighted. These catalysts play a significant role in removing impurities, as sulfur and other hetero-atoms existing in these oil fractions. These catalysts are composed of mainly, molybdenum salts spread in the porous structure of the carrier, mainly γ-Alumina (γ-Al2O3). Other metal salts supporting the action of the catalytic activity of Molybdenum, as Cobalt, Nickel, are added. The first step in the process of catalyst production is the drying of the wet salts mixture to remove moisture. The oxidic precursor is produced by the calcination of the dried mixture. The choice of the appropriate catalyst is based on its ability to maintain a high level of activity for long periods before re-activation. This ability depends on the chemical composition and on the porous structure of the carrier, which ensures the appropriate properties such as the density of active centers, particle strength, and porous structure parameters. Also, the catalyst resistance to chemical poisons destroying active centers in particular, is considered as a limiting factor in selecting the catalyst.
