Abstract: The reforming of CH₄ with CO₂ to produce syngas is not only beneficial to the rational utilization of natural gas resources and mitigation of greenhouse gas emissions, but also can be used to store solar energy and nuclear energy by effectively utilizing the reversible and strong heat absorption process of the reforming reaction. Therefore, it has received widespread attention from academia as well as industry worldwide. In this study, hydroxy aluminum columnar vermiculite was obtained by using Xinjiang Yuli vermiculite ore, which was acidified with HNO₃, cauterized at 600 ℃, exchanged with NaCl, and intercalated with Keggin ions in order to obtain hydroxy aluminum columnar vermiculite. A series of Ni-loaded catalysts (12Ni-CPVMT, 12Ni-2CaO-CPVMT, 12Ni-2MgO-PCVMT) were prepared for methane reforming reaction using column-supported vermiculite as the carrier. The results showed that the activity of 12Ni-CPVMT was only 17 h and the conversion of CO₂ was low. 12Ni-2CaO-CPVMT and 12Ni-2MgO-PCVMT showed high catalytic activity and stability within 3 h of reaction, but deactivation was subsequently observed. 12Ni-2MgO-CPVMT catalyst, after 22 h of reaction, reduced the conversion of methane to 17.94%. In contrast, 12Ni-2CaO-CPVMT showed high stability within 24 h of the reaction, and the conversion of methane was reduced by only 1.28%. This may be related to its interlayer structure and the metal oxides in the swollen vermiculite.
