Hydrodesulfurization (HDS)

Hydrodesulfurization is a valuable cornerstone in the modern refineries, aiming to reduce sulfur-containing compounds to produce cleaner end-products, by using heterogeneous metal catalysts at elevated temperatures and hydrogen pressures.

HDS Catalysts Contain a Mixture of  Either Nickel and Molybdenum or Cobalt and Molybdenum.
