That's the ultimate goal. > Ambitious goal, unless they are doing as the Steinberg & Dong 1998 patent: 5,767,165 suggests: Quote. " The molten materials most advantageously employed herein include molten iron (Fe), molten tin (Sn) and molten salt (NaCL, NaF), with the iron or tin being preferred since the difference in density between the molten metals (iron and tin) and the carbon is greater than between the salt and carbon materials, thereby making the physical separation of the carbon from the molten material easier. In addition, it has been found that a molten material reactor operating at or greater than 800.degree. C. and 1 to 10 atm. pressure results in almost complete decomposition of the methane of more than 90% into carbon and hydrogen gas."
and are concurrently blowing CH4 and H2O (steam) through a bed of molten Tin (mp ~230 C bp 2260 C) and making CO + 3 H2 followed by the CO + H2O ---. CO2 + H2 . Not bad. Otherwise water is about 30% dissociated at 3,000 K, and Hess' Law still applies no mater what the temperature: "the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps" > > I see also they are getting methane from landfills.
