摘要

摘要制备了一系列不同摩尔比的 CeO2-MgO 催化剂，用于等离子体活化 CO2 分解为 CO 和 O2。催化剂采用溶胶-凝胶法合成，并通过物理化学方法（XRD、SEM、XPS、低温 N2 吸附、CO2-TPD）进行表征。在 CeO2 含量最高的催化剂存在下，二氧化碳转化率最高（31%）。还研究了在二氧化碳分解体系中加入 H2 的情况。在合成催化剂存在的情况下，没有发生 CO2 甲烷化，但由于分子氢存在时放电功率增加，观察到 CO2 到 CO 的转化率增加。

Carbon Dioxide Utilization Using Plasma Reactor Packed with Magnesia-Ceria Catalysts with Various Morphology

Abstract

A series of CeO₂–MgO catalysts with different molar ratio was prepared for the plasma-activated CO₂ decomposition to CO and O₂. The catalysts were synthesized by the sol-gel method and characterized by physicochemical methods (XRD, SEM, XPS, low-temperature N₂ adsorption, CO₂-TPD). The highest CO₂ conversion (31%) was achieved in the presence of the catalyst with the highest CeO₂ content. The addition of H₂ into a CO₂ decomposition system was also studied. No CO₂ methanation occurred in the presence of synthesized catalysts, though an increase in the CO₂-to-CO conversion was observed due to an increase of a discharge power in the presence of molecular hydrogen.

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
