Wheat-Straw-Derived Activated Biochar as a Renewable Support of Ni-CeO2 Catalysts for CO2 Methanation
Ceria- and urea-doped activated biochars were used as support for Ni-based catalysts for CO2 methanation purposes. Different materials were prepared and tested to find the best catalytic formulation. After several CO2 methanation experiments—carried out at 0.35–1.0 MPa and 300–500 °C—it was found that the most suitable catalyst was a wheat-straw-derived activated biochar loaded with 30 wt.% of CeO2 and 20 wt.% of Ni. Using this catalyst, a CO2 conversion of 65% with a CH4 selectivity of 95% was reached at 1.0 MPa, 400 °C, and 13,200 h−1. From the study of the influence of the gas hourly space... Mehr ...
