Ni/ZrO₂-Al₂O₃ catalysts were prepared by different methods such as modified Pechini sol-gel, urea hydrolysis, and physical mixing, and were evaluated by the dry reforming of methane under the conditions of reaction temperature of 700°C, an atmospheric pressure, and a space velocity of 25,000 h⁻¹. It was established that the interaction between nickel and support in the dry reforming of methane depends on the preparation methods of catalyst, and plays an important role in terms of the resistance to carbon formation. From the results, we suggested that the Ni/ZrO₂-Al₂O₃ catalyst prepared by Pechini sol-gel showed higher stability under the tested reaction conditions. These results are interpreted that the interaction between nickel and ZrO₂-Al₂O₃ promotes the dissociation of CO₂. It was considered that the catalytic stability in the dry reforming of methane over Ni/ZrO₂-Al₂O₃ catalyst was maintained by the balance for the reaction of deposited carbon and oxygen intermediate derived from the dehydrogenation of methane and the dissociation of CO₂. The results are concluded that the Ni/ZrO₂-Al₂O₃ (PS) catalyst is a desirable catalyst with the resistance to carbon formation in the dry reforming of methane.

Ni / ZrO ₂ -Al ₂ O ₃催化剂是通过改性的Pechini溶胶-凝胶，尿素水解和物理混合等不同方法制备的，并在700℃的反应温度下通过甲烷的干重整进行了评估。℃，大气压和25,000h ^-1的空速。已经确定，镍与甲烷在干法重整中的载体之间的相互作用取决于催化剂的制备方法，并且在抗碳形成方面起着重要的作用。从结果可以看出，由Pechini溶胶-凝胶制备的Ni / ZrO ₂ -Al ₂ O ₃催化剂在测试的反应条件下显示出更高的稳定性。这些结果解释为镍与ZrO ₂ -Al ₂ O ₃之间的相互作用促进了CO ₂的解离。。认为通过Ni / ZrO ₂ -Al ₂ O ₃催化剂的甲烷干重整中的催化稳定性通过甲烷脱氢和CO ₂分解产生的沉积碳和氧中间体反应的平衡得以维持。。结果表明，Ni / ZrO ₂ -Al ₂ O ₃（PS）催化剂是理想的催化剂，在甲烷的干重整中具有抗碳形成的能力。
