Synthesis and Evaluation of K-Promoted Co3-xMgxAl-Oxides as Solid CO2 Sorbents in the Sorption-Enhanced Water−Gas Shift (SEWGS) Reaction
Hydrogen is essential in a variety of large-scale chemical processes. As a carbon-free energy carrier, hydrogen has a potential for wide use within power production and transportation. However, most of the recent production methods involve the release of CO2 as a by-product. Hence, decarbonization...
Preparation and evaluation of new sorbent materials for the Sorption Enhanced Water-Gas Shift (SEWGS) reaction
In-situ XRD studies of dolomite based CO2 sorbents
Calcined dolomite (a CaOMgO material derivative of the natural mineral dolomite) has the potential as a CO2 sorbent working at high temperatures (500-650 °C) in processes like post combustion carbonate-looping, or in sorbent enhanced reactions such as sorbent-enhanced water-gas shift (SEWGS) or...
Studies of Ca-based high temperature sorbents for CO2 capture
The natural mineral dolomite has been calcined and impregnated with Ti-, Zr-, Al-nanoparticle suspensions with the aim of improving the cyclic stabilities in high temperature CO2 sorption processes. After impregnation and subsequent calcination the materials were characterized by N2 adsorption (BET...
Continuous hydrogen production by sorption enhanced steam methane reforming (SE-SMR) in a circulating fluidized bed reactor: Sorbent to catalyst ratio dependencies
Continuous hydrogen production by sorption enhanced steam methane reforming (SE-SMR) has been studied using a circulating fluidized bed reactor with calcined natural dolomite as CO2 sorbent and Ni/NiAl2O4 as catalyst. A steam to methane ratio of 4 was used at 575 °C and ambient pressure. Two...
