Carbon formation and sintering remain the main culprits regarding catalyst deactivation in the dry and bi-reforming of methane reactions (DRM and BRM, respectively). Nickel based catalysts (10 wt.%) supported on alumina (Al₂O₃) have shown no exception in this study, but can be improved by the addition of tin and ceria. The effect of two different Sn loadings on this base have been examined for the DRM reaction over 20 h, before selecting the most appropriate Sn/Ni ratio and promoting the alumina base with 20 wt.% of CeO₂. This catalyst then underwent activity measurements over a range of temperatures and space velocities, before undergoing experimentation in BRM. It not only showed good levels of conversions for DRM, but exhibited stable conversions towards BRM, reaching an equilibrium H₂/CO product ratio in the process. In fact, this work reveals how multicomponent Ni catalysts can be effectively utilised to produce flexible syngas streams from CO₂/CH₄ mixtures as an efficient route for CO₂ utilisation.

碳的形成和烧结仍然是甲烷反应在干法和双向重整中催化剂失活的主要罪魁祸首（分别为DRM和BRM）。负载在氧化铝（Al ₂ O ₃）上的镍基催化剂（10 wt。％）在本研究中没有例外，但可以通过添加锡和二氧化铈来进行改进。在选择最合适的Sn / Ni比并用20 wt。％的CeO ₂促进氧化铝碱之前，已经研究了在20 h内DRM反应中两种不同Sn负载对该碱的影响。。然后，该催化剂在BRM中进行实验之前，应在一定温度和空速范围内进行活性测量。它不仅显示出良好的DRM转化率，而且还显示出稳定的BRM转化率，在此过程中达到了平衡的H ₂ / CO产物比。实际上，这项工作揭示了如何有效地利用多组分Ni催化剂从CO ₂ / CH ₄混合物生产柔性合成气物流，作为利用CO ₂的有效途径。
