Hydrodenitrogenation of pyrrole over ruthenium phosphide catalyst

Abstract

Catalytic activity of ruthenium phosphide for hydrodenitrogenation (HDN) of pyrrole was studied. The HDN activity of Ru catalyst remarkably decreased with increasing reduction temperature. On the other hand, the optimal reduction temperature for HDN activity of Ru-P catalyst was 600 °C. This result was explained by formation of Ru₂P. The Ru catalyst showed high selectivity for cracking products. However, the Ru-P catalyst showed high selectivity for C4 hydrocarbons. In low W/F condition, the Ru-P catalyst showed high and stable HDN activity than Ru catalyst.
