Preparation of Fe2P and FeP catalysts for the hydrotreating reactions

The Fe2P/C and FeP/C catalysts were prepared through the phosphidation of a reduced 60%Fe/C by PPh3 in liquid phase at 543 and 593 K, respectively. The FeP was found to be stable and active, while the Fe2P was much less stable and hence generally less active than FeP, for the hydrotreating reactions.238
