Sumario:[Image: see text] The greenhouse gas reduction as well as the utilization of more renewable and clean energy via a dry reforming reaction is of interest. The impact of a CeMgZnAl oxide quad-blend-supported Ni catalyst on performance and anticoking during dry reforming reactions at 700 °C was studied. A high Ce–Mg/Zn ratio, as seen in the CeMg0.5ZnAl-supported nickel catalyst, enhances lattice oxygen, and the presence of strong basic sites, along with the creation of the carbonate intermediate species, is accompanied by the production of gaseous CO through a gasification reaction between the carbon species and Ni-CO(ads-lin) site. The phenomena caused the outstanding performance of the Ni/CeMg0.5ZnAl catalyst—CH(4) (84%),CO(2) (83%) conversions, and the H(2)/CO (0.80) ratio; moreover, its activity was also stable throughout 30 h.
