Validation of the H2 production stage via SER under relevant conditions for the Ca/Cu reforming process practical application

The total operation pressure (from 1 to 9 bar) did not have an important influence on H2 yield, and/or materials performance. Sorbent carbonation reaction rates up to 4.42 * 10−2 kmol h−1 kg sorb−1 were determined in the experiments, being this parameter responsible of the limit in CH4 space velocity that can be successfully converted through this sorbent/catalyst system. The experimental results have been successfully described by a pseudo-homogeneous reactor model that incorporates the main kinetic expressions of the reactions involved in the SER stage.
