TÓM TẮT
At a large industrial scale, hydrogen is mainly produced from natural gas as feedstock via methane steam reforming. The latter is a highly intensive energy process, leading to high cost and high environmental impact of the final product. Alternative ways for producing green hydrogen with low environmental impact have largely been studied during the last decades. Among them, the valorization of landfill gas, containing mainly methane and carbon dioxide, into green hydrogen, via dry reforming of methane (DRM) appears as a promising route. In fact, DRM allows converting both CO2 and CH4 into syngas. However, catalysts in DRM have usually problems of being deactivated during the reaction, due to thermal sintering at high temperatures (700–950 °C) or due to solid carbon deposition. This paper mostly focuses on the stability of a hydroxyapatite-supported nickel catalyst and its generation in DRM reaction.
