Hydroprocessing catalysts for heavy oil fractions have been originally developed for the counter measurement of air pollution and recently used for many purposes such as upgrading of product, RFCC pretreating and conversion to lighter fractions. In this review, hydrodesulfurization (HDS) and hydrodemetallization (HDM) catalysts were compared with those for lighter fractions. The hydroprocessing catalysts for heavy oil have to treat not only S but also vanadium in feedstock. Because heavy oil has larger molecular size and less reactivity than lighter fractions, larger pore diameter and severer reaction condition should be selected than those for lighter fraction, In general, three type of catalysts such as descale, HDM and HDS catalysts are practically combined to get optimum performance. Additive into catalyst and reaction atmosphere as well as optimization of reaction condition have been investigating to get better performance.
