Abstract

The catalytic conversion of CH₄ by O₂ into syngas (known as partial oxidation of methane; POM) is a practical approach for depleting CH₄ concentration as well as achieving excellent H₂ yield with high H₂/CO ratio. The pentasil zeolite family having different SiO₂/Al₂O₃ ratios 10, 20, 25, and 30 (abbreviated as CBV10A, CBV20A, CP810E, and CBV3024E) is found to be an excellent carrier for Ni. These Ni-containing molecular sieves are investigated for POM and characterized by X-ray diffraction, Raman-infrared spectroscopy, thermogravimetry, temperature-programmed techniques, and transmission electron microscopy. 5Ni/CBV3024E catalyst has smaller number of active sites, 5Ni/CP810E contains unstable active site and mordenite-based Ni catalysts (5Ni/CBV10A and 5Ni/CBV20A) attain higher metal-support interaction. 5Ni/CBV20A outperforms others due to the presence of reducible NiO under moderate and strong interaction. It shows an initial 40% H₂ yield at 600 ^oC and 81% H₂ yield at 750 ^oC. The high-temperature POM reaction limits the H₂/CO ratio close to the stoichiometric value of POM (~ 2), indicating the direct pathways of POM reaction at high temperatures. The high POM activity with the option of a wide range of H₂/CO (4.12–2.26) using Ni-containing molecular sieve may gain industrial-level attention in the coming future.
