Abstract

This paper describes a staged carbonation process for magnesium silicate mineral carbonation. This carbon dioxide capture and storage (CCS) alternative involves the production of magnesium hydroxide, followed by its carbonation in a pressurised fluidised bed (PFB) reactor that is operated at temperatures and pressures so far up to 873 K, 4.5 MPa. The goal is to utilise the heat of the carbonation reaction to drive the Mg(OH)₂ production step. The results show that Mg(OH)₂ can be produced successfully and efficiently from different serpentinite minerals from locations worldwide (Finland, Lithuania, Australia and Portugal). From the extraction step, ammonium sulphate is recovered while iron oxides (from the mineral) are obtained as by-products. The carbonation step, while still being developed, resulted in >50 %-wt conversion in 15 minutes (773 K, 2 MPa) for > 300 urn serpentinite derived Mg(OH)₂ particles.
