Abstract
Biogas dry reforming is a widely concerned technology which converts biogas into syngas. Many attempts have been taken for the synthesis of reforming catalysts. Industrial solid waste such as steel slag and coal fly ash is produced in large amount, which is rich metal oxides thus provides the feasibility in catalysis application. Here we propose the idea of combination of industrial waste utilization and biogas dry reforming. We used two-step activated coal fly ash as supports to synthesize catalysts. The activation measurements were useful for increasing the surface area and pore volume of support. BET and XRF analysis confirmed the changes in elemental composition. During reaction, the catalysts were found to be effective with CH4 and CO2 conversion rates > 95% at 850°C. Metal–support interaction was revealed by H2-TPR profiles of fresh catalysts. The catalysts we prepared was competitive compared with the traditional Ni/SiO2. This is a new approach for biogas dry reforming catalyst synthesis and high-value utilization of solid waste.
