Abstract

Carbon monoxide generation from the splitting of CO
is of greater
importance now than ever before due to continuous increase in CO
2
levels
in the atmosphere and concerns on the sustainability of energy and
environment. This thesis examines the conversion of CO
to CO via
thermochemical redox looping of metal oxides. Oxides of Mg/Fe and
Mg/Al/Fe prepared from layered double hydroxide (LDH) were explored
to aid in the conversion of CO
to CO. The prepared metal oxides from
LDH offered superior stability of porous metal structure and sustained
2
redox capability at moderate to high temperatures required for
conversion. The formations of these metal oxides from LDH were
analyzed using thermogravimetric analysis (TGA). The results showed
635 μmol CO/g of Mg/Fe oxides as compared 557 μmol CO/g from
Mg/Al/Fe. Continuous operation resulted in some sintering effects with
deteriorated redox performance. The redox capability of Mg/Fe oxide
over multi-cycle operations was lower as compared to Mg/Al/Fe oxides,
which showed significant thermal stability while maintaining high CO
yield and redox capability over extended redox cycles.
