Paper Title:
Application of Pd/C Catalyst to Degradation and Utilization of Nitrobenzene in Water
  Abstract

Nitrobenzene(NB) is a highly toxic and resistant to degradation organic pollutant which has been widely distributed in industrial wastewater. Much more attentions on the degradation of NB have been attracted to achieve the effectively removal of organic pollutant. Based on the hydrogen production from aqueous-phase reforming (APR) of oxygenated hydrocarbons reported by Dumesic, a novel method for the catalytic degradation of NB by APR reaction in wastewater has been proposed in this study. The effects of reaction conditions, such as temperature, the initial concentration of NB were investigated over Pd/C catalyst. The experimental results indicated that the degradation degree of NB could reach 100% (NB could be degraded completely) under optimal reaction conditions: 0.75 g 5% Pd/C, 2000 mg/L NB, T = 493 K, P = 3 MPa, t = 6 h under the atmosphere of Ar with a stirring speed of 950 r/min. The deactivation of Pd/C catalyst had not been observed after being reused for 12 recycles (the degradation degree of NB was more than 97%).
