Принадлежит:

A catalyst for hydrogenating the C5 fraction of petroleum to prepare pentane is composed of the carrier (Al2O3) and carried active components including Pd (0.1-1.0 wt.%) and the component A (0.5-1.8 wt.%) which is the mixture of Mo, Cu, or Zn. Its advantages are high output rate and purity of pentane, no poisoning by oxygen-contained groups, and gentle hydrogenating condition.
