摘要

以10% Co/Al2O3和3% Ce-10% Co/Al2O3为催化剂，在常压923-998 ?K代表合成气生产。采用BET、H2-TPR、XRD和拉曼光谱对催化剂进行了表征。Ce促进剂的加入有利于Co3O4的还原，降低了还原温度，增强了金属的分散性。Ce促进还通过提高反应物转化率、合成气产量和减少不良甲烷生成来改善EGDR性能。乙二醇的转化率和H2的产率分别达到71.7%和69.3%。

Ethylene glycol dry reforming for syngas generation on Ce-promoted Co/Al2O3 catalysts

Ethylene glycol dry reforming (EGDR) was investigated for the first time on 10% Co/Al₂O₃ and 3% Ce–10% Co/Al₂O₃ catalysts at stoichiometric feed composition under atmospheric pressure and 923–998?K for syngas production. Catalysts were characterized using BET, H₂-TPR, XRD and Raman spectroscopy measurements. The addition of Ce promoter eased the reduction of Co₃O₄ with lower reduction temperature and enhanced metal dispersion. Ce promotion also improved EGDR performance by increasing reactant conversions, syngas yields and reducing undesirable methane formation. The conversion of ethylene glycol and H₂ yield reached up to 71.7% and 69.3%, respectively.
