Inspection over carbon deposition features of various nickel catalysts during simulated biogas dry reforming

Dry reforming is a promising new technology for biogas utilization. Herein, Ni catalysts using Al2O3, SiO2, MgO, CeO2 and ZnO as supports were prepared and studied to uncover the correlation between physico-chemical properties and activity, also their specific response to carbon formation. The catalysts were characterized systematically via N2-physisorption, XRD, TEM, EDS, H2-TPR, XPS and TGA. The catalytic activity was investigated at 600–850...
