Ethylene Glycol Dry Reforming for Syngas Generation on Ce-promoted Co/Al 2 O 3 Catalysts

Ethylene glycol dry reforming (EGDR) was investigated for the first time on 10% Co/Al 2 O 3 and 3% Ce–10% Co/Al 2 O 3 catalysts at stoichiometric feed composition under atmospheric pressure and 923–998 K for syngas production. Catalysts were characterized using BET, H 2 -TPR, XRD and Raman spectroscopy measurements. The addition of Ce promoter eased the reduction of Co 3 O 4 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 H 2 yield reached up to 71.7% and 69.3%, respectively.
