Catalytic performance of novel Ni catalysts supported on SiC monolithic foam in carbon dioxide reforming of methane to synthesis gas

摘要

Carbon dioxide reforming of methane to synthesis gas has been investigated with Ni catalysts supported on SiC monolithic foam.The structure and properties of the catalysts were characterized by BET,SEM and XRD techniques.The novel catalysts exhibited not only the highest activity but also remarkable stability.Of which,7 wt%Ni/SiC showed the highest activity at 750 °C,During the 100 h performance testing experiment on stream,the conversion of CH4 and CO2 remained almost constant,at about 94.0% and 95.0%,respectively.
