coal has reached a rank of bituminous (Rightmire, 1984). After the temperature exceeds 210 degrees Fahrenheit carbon dioxide production increases with little production of methane. The thermogenic production of methane does not exceed the production of carbon dioxide in high volatile high ranks of coal until the temperature is about 250 degrees Fahrenheit. The maximum generation of methane in bit

High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
