Abstract
Published data on plasma-assisted carbon dioxide methane reforming using heterogeneous catalysts are analyzed. The pathways of the CH4 and CO2 transformation under the conditions of thermal catalysis, plasma action, and plasma-assisted catalysis are considered. Various types of plasma installations are described. The mechanisms of the formation of oxygenates under the conditions of plasma-assisted catalysis are presented. The process selectivity with respect to final products depends on the ratio of the gases and on the structure, dielectric properties, and composition of the catalysts. The important parameters influencing the oxygenate ratio are the metal oxidation state in the catalyst, kind of metal, and support acidity. The catalyst introduction into the plasma can also lead to negative phenomena, namely, to recombination of radicals into the starting compounds.
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.
