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.

Ce促进的Co / Al 2 O 3催化剂的乙二醇干重整制合成气

乙二醇干重整（EGDR）在10％Co / Al ₂ O ₃和3％Ce-10％Co / Al ₂ O ₃催化剂上以化学计量进料组成在大气压下以923-998 K进行了首次研究。生产。使用BET，H ₂ -TPR，XRD和拉曼光谱测量法表征催化剂。Ce促进剂的添加以较低的还原温度和增强的金属分散性促进了Co ₃ O _4的还原。铈的促进还通过增加反应物转化率，合成气产率并减少不希望的甲烷形成而改善了EGDR性能。乙二醇与H ₂的转化 产率分别达到71.7％和69.3％。
