Comparison of novel olivine supported catalysts for high purity hydrogen production by CO2 sorption enhanced steam reforming

Seven Ni-based catalysts were prepared over different supports (conventional Al2O3, non-conventional olivine and hydrotalcite) with Co and Pd addition. Their catalytic performance was studied in hydrogen production by Steam Reforming (SR) and CO2-Sorption Enhanced Steam Reforming (SESR) with two dif...
