A chemical heat pump to generate high-temperature heat at a temperature hotter than the original source
Please, see [5] for details and mass and energy balances
Heat Q (T1 < 873K) is suplied by a nuclear reactor Increasing steam temperature by elevating the coolant temperature higher than
an established limit is detrimental to the nuclear reactor safety
Heat Q(T > T1) is generated in Methanation Reactor and Q(T < T1) consumed in Reformer due to a shift in chemical equilibrium by an excess of steam Reaction mixture: H2, CO, CH4, H2O
Methanation reactor: 3H2 + CO → CH4 + H2O (steam) + Heat released (at T > T1 )
Reformer: CH4 + H2O (excess) → 3H2 + CO + Heat consumed (at T < T1)
