Hydrogen‐rich syngas production from bi‐reforming of greenhouse gases over zirconia modified Ni/ <scp>MgO</scp> catalyst

Bi-reforming of methane (BRM) is gaining an increase interest due to the critical requirements mitigate global warming and provide alternative energy resources. However, there has been a serious challenge scale-up process commercial production catalyst deactivation. In present study, influence ZrO2 modifications on activity stability MgO-supported Ni in BRM reaction was investigated. The ZrO2-MgO mixed oxide support prepared by co-precipitation method with variation composition subsequently impregnated Ni. characterization freshly Ni/MgO Ni/MgO-ZrO2 catalysts using N2 physisorption analysis, X-Ray Diffraction (XRD), FESEM, XPS, H2-TPR, CO2-TPD techniques revealed suitable physicochemical properties for reaction. showed improved performance terms compared at 800°C CH4, H2O, CO2 ratio 3:2:1, respectively. best obtained Ni/15%ZrO2-MgO CH4 conversion 81.5% 82.5%, spent Raman spectroscopy, High Resolution Transmission Electron Microscopy (HRTEM) analysis formation amorphous carbon that could be responsible its fast
