【 摘 要 】

Carbon dioxide reforming of ethanol over Rh/CeO2 catalyst was deeply investigated at different reaction temperatures of 450–700 °C and reactant ratios (CO2/ethanol from 1 to 3) under atmospheric pressure. The obtained results indicated that Rh/CeO2 catalyst presented a promising activity and stability for syngas production from renewable bio-ethanol instead of conventional methane. Typically, CO2-rich conditions (CO2/ethanol = 3) were favorable for reaction process and dynamic coke cleaning, which led to remarkably stable performance over 65 h on stream. The strong redox capacity of CeO2 support might also accelerate CO2 activation and prevent the carbon accumulation over the catalyst surface. Additionally, tunable H2/CO ratios were available by changing the CO2/ethanol ratios. The results from characterization of samples before and after catalytic tests allowed to establish the relationship between textural properties and catalytic performance.
