Title
(EN) ZIRCONIA-STABILIZED CALCIUM OXIDE NANOPARTICLES FOR CO2 CAPTURE AT HIGH TEMPERATURES
(FR) NANOPARTICULES D'OXYDE DE CALCIUM STABILISÉES PAR DE LA ZIRCONE POUR LA CAPTURE DE CO2 À DES TEMPÉRATURES ÉLEVÉES
Abstract
(EN)
The invention provides highly reactive nanosized calcium oxide particle compositions, including calcium oxide compositions with a BET surface area of 200 m2/g. Also disclosed are stabilized calcium oxide sorbents comprising material that consists of metal oxides. Methods for the synthesis and fabrication of these compositions are provided, along with methods for the use of these compositions as sorbents.
