ABSTRACT
In this paper, sugarcane bagasse was used as the raw material to produce hydrochar (HC) through the hydrothermal carbonization (HTC) process, then Ni and Mg were loaded on HC by the impregnation method. Thus, a serial of Ni-Mgx@HC core-shell structural catalysts for CO2 dry reforming were synthesized. In order to evaluate the application of Ni-Mgx@HC catalyst derived from sugarcane bagasse, the catalytic performance for CO2 dry reforming were investigated. Experimental results showed that the hydrochar based catalyst (Ni-Mg15@HC) exhibited an excellent activity and stability at 750°C, CH4 and CO2 conversions were 63.7% and 76.9%, respectively. XRD, TEM, CO2-TPD and TG-DTG characteristic proved that the addition of Mg into Ni@HC would promote the active site formation and the adsorption capacity of CO2. Moreover, the coke deposition was also suppressed in the DRM process. The catalytic performance of Ni-Mg15@HC catalyst demonstrated that it was a practical candidate for the DRM reaction due to its unexpected activity and stability.
