Abstract

Effective catalysts of CO₂ hydrogenation towards methane were obtained by impregnation of aluminum oxide with cobalt and iron nitrates. The catalysts have been characterized by XRD, SEM-EDX, argon physisorption, and TPD with mass-spectroscopy analysis. It is shown that an increase in the amount of applied Co-Fe active mass in the composition of a nanocomposite catalyst leads to an increase in the CO₂ conversion and CH₄ yield.

Co-Fe/Al2O3纳米复合催化剂在CO2加氢过程中的应用

用硝酸钴和硝酸铁浸渍氧化铝，得到了CO2加氢制甲烷的有效催化剂。采用XRD、SEM-EDX、氩气物理吸附和质谱分析对催化剂进行了表征。结果表明，纳米复合催化剂中Co-Fe活性质量的增加可导致CO2转化率和CH4产率的提高。
