Abstract

Bentonite clays containing montmorillonite are a nanostructure family of the smectite and have several industrial applications, such as the carrier for the preparation of the nickel‐based catalysts for the syngas production via methane reforming with carbon dioxide. In this article, the physicochemical properties of the samples were determined by different analyses such as X‐ray fluorescence, X‐ray diffraction Brunauer–Emmett–Teller, thermal gravimetric analysis, Fourier transform infrared spectroscopy, scanning electron microscopy, H2 temperature‐programmed reduction, and swell index. Four natural bentonites were studied, and the sample with the surface area of 38.2 m2 g−1, pore diameter of 8.15 nm, and the highest content of montmorillonite was selected for pillaring process with aluminum. The results demonstrated that the pillaring process significantly improved the Brunauer–Emmett–Teller area. The catalytic results also confirmed that the 10% Ni catalyst supported on pillared clay demonstrated higher catalytic performance and resistance against carbon deposition compared with the catalyst supported on natural clay in methane reforming with CO2 (dry reforming of methane reaction).
