A kinetic study of the CO₂ desorption process by carbonated sodium zirconate (Na₂ZrO₃) synthesized by a liquid suspension route is presented using zirconium acetylacetonate and sodium acetate as precursors. Na₂ZrO₃ was characterized by XRD, SEM and TGA. Na₂ZrO₃ exhibited a 90% conversion during absorption with respect to the theoretical value. CO₂ desorption kinetic study used three temperatures; 850, 900 °C and 950 °C and three concentrations: 5, 3 and 1% of CO₂ in Ar at 200 ml/min. XRD data shown only slight segregation of the precursors, which led to a small amount of ZrO₂ formation in the solid product. The global rate of the decarbonation reaction of Na₂ZrO₃ was of first order in CO₂ concentration and strongly dependent on temperature. The calculated apparent activation energy was E_A = 23.35 kcal/mol. Na₂ZrO₃ performance during four continuous cycles, shown an excellent thermal and chemical stability, with the material conversion remaining practically unchanged.
