Active and Stable Ni/AlO-(Zr + Ce)O Catalyst for Syngas Production via Glycerol Dry Reforming

A nickel-based catalyst supported on alumina-zirconia-ceria oxides was investigated to evaluate its performance in the dry reforming of glycerol with CO. The reaction was carried out at 700°C, atmospheric pressure and a glycerol/CO molar ratio of 1. The catalyst showed stable operation for 7 h and achieved glycerol and CO conversions of 60 and 47%, respectively, with H and CO yields of 48 and 58%. Thermogravimetric analysis revealed the presence of carbon deposits, which, however, did not result in a significant loss of activity. These results highlight the potential of the synthesized catalyst for glycerol conversion for the production of syngas and hydrogen from renewable feedstock.
