Hollow Submicrospherical Ni/Co-Promoted CaO/Ca 12 Al 14 O 33 for H 2 Production from Sorption-Enhanced Water–Gas Shift with In Situ CO 2 Conversion via CH 4 Reforming of CaCO 3

CaO sorbent/catalyst bifunctional materials are promising for CO2 capture in sorption-enhanced H2 production such as sorption-enhanced water–gas shift. For simultaneous H2 production with CO2 in situ capture and utilization, the integrated process of sorption-enhanced water–gas shift and in situ CO2 conversion by CH4 reforming of CaCO3 was proposed. This work focused on the tailored design of a CaO sorbent/catalyst bifunctional material for both efficient H2 production and in situ CO2 conversion in this integrated process. The template-assisted strategy of hydrothermal carbonization followed by self-reduction and template removal via steam gasification was first proposed to obtain the hollow submicrospherical…
