Tri-reforming of methane was examined over Ni/Mg/Al hydrotalcite-derived catalyst for CO₂ utilization directly from simulated flue gas mixtures from natural gas-fired power plants. This catalyst showed promising results for the studied experimental conditions, revealing the following order of CH₄ conversion: TRM3 (75.9 %) < TRM2 (91.9 %) < TRM1 (98.2 %). The activity trend was related to the Ni crystallite size, with smaller particles leading to increased conversion. The highest TOF value was found for gas feed with elevated CH₄ concentration (TRM3), possibly due to a significant contribution of side reactions parallelly occurring during tri-reforming of methane. The HTNi catalyst after TRM3 showed bigger Ni⁰ particles, which are prone to participate in the formation of graphitic-like carbon. The presence of encapsulated Ni particles and carbon nanotubes was confirmed by XRD, TGA, HRTEM, and ToF-SIMS for HTNi used in TRM3.

直接从天然气发电厂的模拟烟气混合物中，对Ni / Mg / Al水滑石衍生的催化剂进行了甲烷三重整，以检测CO _2的利用。该催化剂在所研究的实验条件下显示出令人鼓舞的结果，揭示出CH ₄转化的顺序如下：TRM3（75.9％）<TRM2（91.9％）<TRM1（98.2％）。活性趋势与镍微晶尺寸有关，较小的颗粒导致转化率增加。对于CH ₄浓度升高的气体进料（TRM3），发现最高的TOF值可能是由于甲烷三重整过程中平行发生的副反应的重要影响。TRM3之后的HTNi催化剂显示较大的Ni ⁰容易参与形成石墨状碳的颗粒。XRD，TGA，HRTEM和用于TRM3的HTNi的ToF-SIMS证实了封装的Ni颗粒和碳纳米管的存在。
