不饱和烃中含有的微量氧会使后序装置受到影响，因而必须全部脱除。该催化剂适用于低温配氢脱氧，能有效脱除不饱和烃中吸附的痕量游离氧。例如，在低压羰基合成制备丁辛醇的原料液相丙烯中，微量氧的存在会降低贵金属铑催化剂的活性。使用贵金属Pd/Al₂O₃催化剂，利用H₂-O₂在低温下反应生成水，可以将微量氧除去，而不致发生加氢反应。

Trace oxygen present in unsaturated hydrocarbons can adversely affect downstream units and therefore must be completely removed. This catalyst is designed for low-temperature deoxygenation with added hydrogen, effectively eliminating trace adsorbed free oxygen from unsaturated hydrocarbons.

For instance, in the liquid propylene feedstock used for the low-pressure oxo synthesis of butanol and octanol, the presence of trace oxygen reduces the activity of the precious metal rhodium catalyst. By using a precious metal Pd/Al2O3 catalyst, trace oxygen can be removed through the low-temperature H2-O2 reaction to form water, without triggering unwanted hydrogenation reactions.
