    Hydrotreating processes aim to remove impurities such as sulfur, nitrogen, oxygen, olefins, and metals from distillate fuels like naphtha, kerosene, and diesel. This is achieved by treating the fuel feed with hydrogen at elevated temperature and pressure in the presence of a catalyst. The key impurities—sulfur, nitrogen, and oxygen—are removed through reactions with hydrogen, transforming them into forms that are eliminated from the fuel as water, ammonia, or sulfur compounds. Olefins are also transformed to prevent coking on the catalyst during the high temperature process.

    Distillate Hydrotreating p1

    Hydrotreating processes aim at


    the removal of impurities such as sulfur and nitrogen
    from distillate fuelsnaphtha, kerosene, and diesel
    by treating the feed with hydrogen at elevated temperature and pressure in
    the presence of a catalyst

    The principals impurities to be removed


    Sulfur
    Sulfur-containing compounds are
    mercaptans, sulfides, disulfides,
    polysulfides, and thiophenes
    Nitrogen
    Oxygen
    (dissolved or present In the form of comp.
    (phenols , preoxides after reacting with H2
    eliminated into water
    Olefins
    at high temp. can cause coke deposits on
    catalyst or on furnace so it transformed
    into stable paraffinic HCs
    Metals
