Abstract[English]
Methods of forming a soil amendment from calcium slag silicate include: (a) increasing content of sodium in a bentonite clay via ion exchange by reacting bentonite clay and a sodium salt to provide ion-exchanged sodium bentonite clay; (b) feeding carbon dioxide through a reactor containing a mixture of the calcium slag silicate and the sodium bentonite clay; wherein sodium ions of the sodium bentonite clay adsorb carbon dioxide and form sodium carbonate; (c) feeding calcium silicate through the reactor and reacting the calcium silicate with the sodium bentonite clay in a chain fashion to consume the sodium carbonate and the calcium silicate and form sodium silicate and calcium carbonate; (d) reacting the sodium silicate with the carbon dioxide to re-form sodium carbonate and form silicon dioxide; and (e) combining the generated calcium carbonate and silicon dioxide to form the soil amendment.[French]
Sont divulgués des procédés de formation d'un amendement du sol à partir de silicate de scories de calcium, consistant : (a) à augmenter la teneur en sodium d'une argile bentonite par échange d'ions, par la mise en réaction de l'argile bentonite et d'un sel de sodium afin d'obtenir de l'argile bentonite sodique à ions échangés ; (b) à acheminer du dioxyde de carbone dans un réacteur contenant le mélange du silicate de scories de calcium et de l'argile bentonite sodique ; (c) à acheminer du silicate de calcium dans le réacteur et à mettre en réaction en chaîne le silicate de calcium avec l'argile bentonite sodique afin de consommer le carbonate de sodium et le silicate de calcium et de former du silicate de sodium et du carbonate de calcium ; (d) à mettre en réaction le silicate de sodium avec le dioxyde de carbone pour reformer du carbonate de sodium et former du dioxyde de silicium ; et (e) à combiner le carbonate de calcium et le dioxyde de silicium générés pour former l'amendement du sol.
