摘要： Method for the production of hydrogen from a fuel mixture substantially consisting of methane (CH 4 ) and carbon dioxide (CO 2 ) by means of a hydrogen production plant provided with carbonation reactor and calcination reactor, said method comprising the steps of:
a) feeding said carbonation reactor with said fuel mixture;
b) feeding said carbonation reactor with water vapor (gaseous H 2 O);
c) feeding said carbonation reactor with calcium monoxide (CaO), said calcium monoxide (CaO) at least partially originating from said calcination reactor;
d) production of hydrogen (H 2 ) and calcium carbonate (CaCO 3 ) from said carbonation reactor;
e) feeding said calcination reactor, suitably heated, with said calcium carbonate (CaCO 3 );
f) production of calcium monoxide (CaO) and carbon dioxide (CO 2 ) from said calcination reactor, said calcium monoxide (CaO) and said carbon dioxide (CO 2 ) evolving by said calcium carbonate (CaCO 3 );

characterized in that during said controlled step of feeding said carbonation reactor with calcium monoxide (CaO), the ratio of the calcium monoxide (CaO) moles introduced in the carbonation reactor during step c) to the sum of the methane (CH 4 ) and carbon dioxide (CO 2 ) moles contained in said fuel mixture during the above-mentioned step a) is greater than 1.
