Abstract[English]
Methods of forming a soil amendment include: (a) providing a carbon dioxide source; (b) adsorbing carbon dioxide from the carbon dioxide source with sodium oxide of sodium bentonite clay to form sodium carbonate; (c) reacting the sodium carbonate with an olivine magnesium silicate to consume the sodium carbonate and form magnesium carbonate and sodium silicate; (d) reacting the sodium silicate with carbon dioxide to consume the sodium silicate, re-form sodium carbonate, and form silicon dioxide; and (e) forming the soil amendment by combining the generated magnesium carbonate and the silicon dioxide. Steps (c) and (d) continue in a continuous fashion until the olivine magnesium silicate is consumed. A soil amendment formed according to these methods is also described.[French]
L'invention concerne des procédés de formation d'un amendement des sols consistant : (a) à fournir une source de dioxyde de carbone ; (b) à adsorber le dioxyde de carbone de la source de dioxyde de carbone avec de l'oxyde de sodium d'argile bentonite sodique pour former du carbonate de sodium ; (c) à faire réagir le carbonate de sodium avec un silicate de magnésium olivine pour consommer le carbonate de sodium et former du carbonate de magnésium et du silicate de sodium ; (d) à faire réagir le silicate de sodium avec du dioxyde de carbone pour consommer le silicate de sodium, à reformer du carbonate de sodium et à former du dioxyde de silicium ; et (e) à former l'amendement des sols en combinant du carbonate de magnésium généré et du dioxyde de silicium. Les étapes (c) et (d) continuent d'une manière continue jusqu'à ce que le silicate de magnésium olivine soit consommé. L'invention concerne également un amendement des sols formé selon ces procédés.
