Hydrogen production from simple alkanes and oxygenated hydrocarbons over ceria–zirconia supported catalysts: Review

Metal supported catalysts in hydrogen production reactor has a very broad application prospect. However, the film adhesion of active coating with the metal support is the key problem which needed to be solved urgently. In this paper, FeCrAl alloy was chosen as the metallic substrate. The effects of oxidation temperature and time on the morphology, crystal phase and element composition of the metal surface were investigated by XRD, SEM and EDAX. The results show that after pre-treatment of FeCrAl Metallic Substrate,a dense transition layer of α-Al2O3 formed on the surface of the metallic support. Thus the oxidized α-Al2O3 layer and the γ-Al2O3 coating could combine together better. The optimum pre-treatment condition is at 950°C for 10h in air atmosphere.

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%).
