Recently, attention has been paid to the development of a reforming process that can be used to convert non-combusted natural gas (NG) to value-added products. In this study, a template-free nano-spinel nickel ferrite (Fe₇₀Ni₃₀)-based oxygen carrier is prepared via an ultrasonic assistance method. Its physicochemical properties are characterized using X-ray diffraction, electron paramagnetic resonance, Raman spectra, temperature-programmed reduction, the Brunauer, Emmett and Teller surface area, and transmission electron microscope. The efficiency of Fe₇₀Ni₃₀ is evaluated in CO₂ dry reforming of methane, combined dry-steam reforming of methane, and steam activation chemical looping (CL) reforming under atmospheric pressure and various temperatures (600–700 °C). By controlling the reaction temperature higher hydrocarbons (> CH₄) are formed directly (at 600 °C), or through the produced syngas (H₂/CO ~ 2) at 700 °C which is suitable for the Fischer Tropsch process. In addition, methanol is directly formed and its selectivity increased during the CL reforming reaction under atmospheric pressure and at 700 °C, which considered as mild conditions compared to previously studied methanol production reactions. The prepared Fe₇₀Ni₃₀ catalyst could be used for the reforming of NG streams that contain CH₄, CO₂ and H₂O, which are typical unconventional NG constituents (e.g., of biogenic gas) without complicated pretreatment purification steps.

近来，注意力已经集中在可用于将非燃烧天然气（NG）转化成增值产品的重整方法的开发上。在这项研究中，通过超声辅助方法制备了不含模板的纳米尖晶石型镍铁氧体（Fe ₇₀ Ni ₃₀）基氧载体。使用X射线衍射，电子顺磁共振，拉曼光谱，程序升温还原，Brunauer，Emmett和Teller表面积以及透射电子显微镜来表征其理化性质。在CO _2中评估Fe ₇₀ Ni ₃₀的效率甲烷的干重整，甲烷的干蒸汽重整以及在大气压力和各种温度（600-700°C）下的蒸汽活化化学回路（CL）重整。通过控制反应温度，可以直接（在600°C下）或通过在700°C下生成的合成气（H ₂ / CO〜2）形成较高级的烃（> CH ₄），适用于费托工艺。此外，甲醇是直接形成的，并且在CL重整反应中，在大气压和700°C的条件下提高了选择性，与以前研究的甲醇生产反应相比，这是温和的条件。制备的Fe ₇₀ Ni ₃₀催化剂可用于重整含CH ₄的NG流，CO ₂和H ₂ O，它们是典型的非常规NG成分（例如生物气），无需复杂的预处理纯化步骤。
