Abstract[English]
The invention provides processes for capture of gaseous carbon dioxide in the form of magnesium carbonates, with attrition of friable surface passivation layers on magnesium oxide/magnesium hydroxide particulates to facilitate more complete carbonation of reactive carbon capture particulates.[French]
L'invention concerne des procédés de capture de dioxyde de carbone gazeux sous la forme de carbonates de magnésium, par attrition de couches de passivation de surface friables sur des particules d'oxyde de magnésium/hydroxyde de magnésium pour faciliter la carbonatation plus complète de particules réactives de capture de carbone.
