摘要：
The CO2 reforming of methane on the Rh/Al2O3 catalyst was performed using a flow microreactor at 773-973 K. The effects of the catalyst pretreatment, the ratio of CH4/CO2 and the CeO2 support were studied. The oxidized/reduced Rh/Al2O3 catalyst had a higher activity and the addition Of CO2 significantly enhanced the CH4 reforming to form H-2 and reduced the catalyst deactivation caused by carbon deposition on the active sites. The Rh/CeO2 catalyst was less active during the CH4 reforming with CO2 addition than the Rh/Al2O3 catalyst based on the catalyst weight, whereas the areal activity of Rh/CeO2 was close to Rh/Al2O3.
