nThe main causes for catalyst deactivation for Residue Desulfurization process are coke formation and metal deposition
n
nA combination  between various catalyst such as hydrodemetallation (HDM), hydrodesulfurization (HDS), and hydrodenitrogenation (HDN) will extend catalyst life and meet specification processing objective.  nThe compination of newly development Bimodal HDM&HDS increase run length of Atmospheric Residue Desulfurization (ARD)
