Abstract
This review provides an analysis of prior research on liquid-media methane pyrolysis for hydrogen production. It discusses the experimental studies and reported data on methane pyrolysis in molten metals, molten binary alloys, molten salts, and molten metal–salt media. The experimental data suggest that binary metal alloys are superior to pure metals in terms of catalytic performance. A comparative assessment of catalytic activity showed that the highest performance (methane conversion above 95% at temperatures below 1200°C) has been achieved by molten Ni–Bi and Cu–Bi alloys. Besides the thermobaric conditions and characteristics of the bubbling systems, the media’s reactivity plays a key role in pyrolysis efficiency. The combined use of molten metals and salts as a reaction medium noticeably enhances the methane conversion (due to the catalytic activity of molten metals) and appreciably reduces the content of metal impurities in the carbon product.
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.
