Abstract
A method can include performing a series of reactions in a closed cycle, the series of reactions consisting of a hydrolysis reaction where a redox reagent is oxidized to a corresponding oxidized redox reagent with water contemporaneously with the production of hydrogen; and a reduction reaction where the oxidized redox reagent is reduced to the redox reagent using a sulfurous reactant contemporaneously with production of sulfur dioxide.
Claims20
A method comprising:
- within a thermal reactor, reacting a metal in a two-step reaction consisting of:
- a first reaction comprising:
- introducing water into the thermal reactor;
- heating the thermal reactor to a temperature between 400° C. and 800° C.;
- reacting the metal and the water for a first reaction time between 0.5 seconds and 5 seconds to oxidize the metal into a metal oxide and produce hydrogen;
- and
- a second reaction comprising:
- introducing sulfur into the thermal reactor;
- heating the thermal reactor to a temperature between 900° C. and 1500° C.;
- and
- reacting the metal oxide and the sulfur for a second reaction time between 0.01 seconds and 3 seconds to reduce the metal oxide back to the metal and produce sulfur dioxide;
- and
- repeating the two-step reaction.
