Abstract
(EN)
The present invention describes a process for preparing ceramic materials for the absorption of acid gases, mainly carbon dioxide, in exhaust systems and/or present in closed environments. The ceramic materials are formed of a mixture of an alkaline carbonate and an alkaline earth metal oxide/hydroxide in combination with an agglomerating, but non-limiting, component. The alkaline carbonate comprises sodium or potassium carbonate, or a mixture thereof. The alkaline earth metal oxide/hydroxide can be formed of magnesium oxide or magnesium hydroxide, or calcium oxide and/or calcium hydroxide.
(FR)
La présente invention concerne le procédé de préparation de matériaux céramiques pour absorption de gaz acides, notamment le dioxyde de carbone, dans des systèmes d'échappement et/ou se trouvant dans des environnements fermés. Les matériaux céramiques sont formés par un mélange de carbonate alcalin avec un oxyde/hydroxyde de métal alcalino-terreux en combinaison avec un constituant agglomérant, non limitativement. Le carbonate alcalin comprend du carbonate de sodium, de potassium ou un mélange des deux. L'oxyde/hydroxyde de métal alcalino-terreux peut être formé par de l'oxyde de magnésium ou de l'hydroxyde de magnésium ainsi que de l'oxyde de calcium et/ou de l'hydroxyde de calcium.
(PT)
A presente invenção descreve o processo de preparação de materiais cerâmicos para absorção de gases ácidos, principalmente o dióxido de carbono, em sistemas de exaustão e/ou que presente em ambientes fechados. Os materiais cerâmicos são formados por uma mistura de carbonato alcalino com óxido/hidróxido de metal alcalino terroso associado a um componente aglomerante, mas não limitante. O carbonato alcalino compreende a carbonato de sódio, potássio, ou uma mistura de ambos. O óxido/hidróxido de metal alcalino terroso pode ser formado por oxido de magnésio ou hidróxido de magnésio assim como óxido de cálcio e/ou hidróxido de cálcio.
