Syngas production via CO2 reforming of CH4 over Zr-Ni/SBA-15

In the present study, the effect of Zirconium (Zr) loading (1-7wt %) as promoter on the properties of Ni/SBA-15 catalyst for production of syngas by CO2 reforming of CH4 were studied. Zirconium promoted Ni/SBA-15 catalyst was prepared using one pot sol-gel method as described in the literature [1]....
