The present invention describes the process of preparing ceramics for the absorption of ACIDIC gases, which worsen the greenhouse effect, that are released in combustion systems, or that are present in closed environments. In relation to carbon dioxide, principal target of the present invention, the process of absorption, transport, processing and transformation of the gas into other products is described. The process uses ceramic materials prepared through the solid mixture of one or more metallic oxides, with one or more binding agents and an expanding agent. The product generated can be processed and the absorbent system regenerated. The carbon dioxide obtained in the processing can be used as analytic or commercial carbonic gas, various carbamates and ammonium carbonate.
A ceramic material for absorption, storage, and recovery of CO2, SO3, SO2, NO, and NO2 at 25° C. to 700° C., comprising a solid mixture of one or more metal oxides 80-95% (p/p), one or more binding agents 5-10% (w/w), and an expanding agent 0-2% (w/w).
