Catalytic hydrotreating (HDT) is applied extensively in the petroleum refining industry to remove impurities, such as heteroatoms (sulfur, nitrogen, oxygen), PNAs (polynuclear aromatics), and metal-containing compounds (primarily V and Ni). The concentration of these impurities increases as the boiling point of the petroleum fraction increases. S-, N-, O-, and PNA-containing compounds are found in low-molecular-weight […]
