Preparation of CO₂ Absorbent by Spray Pyrolysis

Li₂ZrO₃ particles were prepared by spray pyrolysis and solid state reaction to compare their CO₂ absorption capacity and rate. The former method provided much higher CO₂ absorption capacity and rate than those by the latter. Spherical particles of rather small and uniform size allow the faster diffusion of Li to the surface for higher CO₂ absorption capacity and regeneration of absorption through CO₂ recovery.
