Catalytic Hydrotreating is a hydrogenation process used to remove about 90% of contaminants such as sulphur, nitrogen and oxygen for the final product specification or the preparation of feed for further processing (naphtha reformer feed or Fluid Catalytic Cracking (FCC) feed). The hydrotreating catalyst is a porous alumina matrix impregnated with combinations of cobalt (Co), nickel (Ni), molybdenum (Mo) and tungsten (W).
Reference Definition by EIA: Catalytic Hydrotreating is a refining process for treating petroleum fractions from atmospheric or vacuum distillation units (e.g. naphthas, middle distillates, reformer feeds, residual fuel oil, and heavy gas oil) and other petroleum (e.g. cat cracked naphtha, coker naphtha, gas oil, etc.) in the presence of catalysts and substantial quantities of hydrogen. Hydrotreating includes desulfurization, removal of substances (e.g. nitrogen compounds) that deactivate catalysts, conversion of olefins to paraffins to reduce gum formation in gasoline, and other processes to upgrade the quality of the fractions.
