the catalyst used in NHT is typically Co-Mo (Cobalt-Molybdenum) or Ni-Mo (Nickel-Molybdenum) on an alumina base.
✔ It promotes hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) reactions.
✔ Helps convert sulfur compounds (e.g., mercaptans, thiophenes) into hydrogen sulfide (H₂S).
✔ Ensures naphtha is sulfur-free before entering the catalytic reformer.
