固体氧化物燃料电池（SOFCs）和生物质气化的结合是一种潜在的有吸引力的清洁和可再生能源生产技术。然而，在生物质气化过程中形成的焦油对SOFC阳极的性能和耐久性的影响尚未得到很好的实验证实。本文报道了在两种市售镍基SOFC负极材料Ni/YSZ（钇稳定氧化锆）和Ni/CGO（掺钆二氧化铈）上，15 g/Nm3苯作为模型生物质气化焦油蒸汽重整产生的碳的热力学预测和实验测量结果的比较。以60:40 wt % NiO/YSZ和50:50 wt % NiO/CGO粉末为催化剂材料进行平行实验，采用程序升温氧化法检测成碳程度。蒸汽的加入减少了两种材料上的碳生成，Ni/CGO比Ni/YSZ的碳生成略多。这可能……
The combination of solid oxide fuel cells (SOFCs) and biomass gasification is a potentially attractive technology for the production of clean and renewable energy. However the impact of tars, formed during biomass gasification, on the performance and durability of SOFC anodes has not been well established experimentally. This paper reports on the comparison between thermodynamic predictions and experimental measurements of carbon formation arising from the steam reforming of 15 g/Nm3 benzene as a model biomass gasification tar over two commercially available nickel-based SOFC anode materials, Ni/YSZ (yttria-stabilized zirconia) and Ni/CGO (gadolinium-doped ceria). Parallel experiments were performed using 60:40 wt % NiO/YSZ and 50:50 wt % NiO/CGO powders as catalyst material, and the degree of carbon formation was examined by temperature-programmed oxidation. The addition of steam reduced carbon formation on both materials, with Ni/CGO showing slightly more carbon formation compared to Ni/YSZ. This could ...
