Abstract
A novel CaO/CuO based composite material (53 wt% CuO/ 22 wt% CaO/ 25 wt% Ca12Al14O33), developed for combined CO2 capture and heat transfer for the Ca/Cu hydrogen production process, showed a maximum CO2 capture rate of 1.53*10-2 kmol CO2/h.kg material, at a linear gas velocity of 0.55 m/s when operating in a fixed bed reactor in presence of a commercial reforming catalyst during methane Sorption Enhanced Reforming (SER). The system was able to convert up to 2.4 kg CH4/h.kg catalyst, producing a gas stream with over 93 % vol. hydrogen (dry basis) at 10 bars for a steam to carbon molar ratio of 3.2.
