Powders of CaO sorbent modified with CaZrO3 have been synthesized by a wet chemical route. For carbonation and calcination conditions relevant to sorbent-enhanced steam reforming applications, a powder of composition 10 wt % CaZrO3/90 wt % CaO showed an initial rise in CO2 uptake capacity in the fir...
