The activity and stability of modified nanoclays surface supported nickel (Ni/NC-x) catalyst were investigated and compared to unmodified nanoclay surface supported nickel (Ni/NC) catalyst in dry reforming reaction (500–800 °C). The nickel metal was loaded on modified nanoclay surface with different alkylammonium modifiers—trimethylstearyl ammonium (NC-T), methyl dihydroxy-ethyl hydrogenated tallow ammonium (NC-M), aminopropyltriethoxysilane and octadecylamine (NC-A), and dimethyl dialkyl amine (NC-D) by using the impregnation method. As a results, the surface area and pore volume of Ni/NC-x catalysts were 1.70–3.96 and 2.33–4.33 times higher than that of Ni/NC catalyst, respectively. A longer chain of alkylammonium ions of modifier enhanced the intercalation of the modifier molecules into the interlayer of the nanoclay. Among these catalysts, the highest surface area of Ni/NC-T catalyst could facilitate the Ni metal dispersion and smaller size of NiO, resulting in the stronger interaction between Ni and NC-T support. It then gave the highest CO₂ and CH₄ conversions and H₂/CO ratio. In addition, H₂ and CO yields of Ni/NC-T catalyst were 1.21 and 1.20 times higher than that of Ni/NC catalyst, respectively. Moreover, the modified nanoclays surface supported nickel catalyst could reduce the carbon formation during the reaction.

研究了改性纳米粘土表面负载的镍（Ni / NC-x）催化剂的活性和稳定性，并将其与未改性纳米粘土表面负载的镍（Ni / NC）催化剂在干重整反应（500–800°C）中进行了比较。用不同的烷基铵改性剂（三甲基硬脂基铵（NC-T），甲基二羟基乙基氢化牛脂铵（NC-M），氨丙基三乙氧基硅烷和十八烷基胺（NC-A）和二甲基二烷基胺（NC））将镍金属负载在改性的纳米粘土表面上。 -D）通过使用浸渍方法。结果，Ni / NC-x催化剂的表面积和孔体积分别比Ni / NC催化剂高1.70–3.96和2.33–4.33倍。改性剂的烷基铵离子的较长链增强了改性剂分子插入纳米粘土中间层的能力。在这些催化剂中，Ni / NC-T催化剂的最大表面积可以促进Ni金属的分散和NiO的较小尺寸，从而使Ni与NC-T载体之间的相互作用更强。然后产生最高的CO₂和CH ₄转化率以及H ₂ / CO比。另外，Ni / NC-T催化剂的H ₂和CO产率分别比Ni / NC催化剂高1.21倍和1.20倍。而且，改性的纳米粘土表面负载镍催化剂可以减少反应过程中的碳形成。
