CERAMIC MATERIALS FOR ABSORBING ACID GASES, PROCESS OF PREPARING SAME AND CYCLIC ACID GAS ABSORPTION AND REGENERATION PROCESS

摘要

The present invention describes a process for preparing ceramics for the absorption of acid, greenhouse effect gases released in combustion systems, or present in closed environments. In relation to carbon dioxide, the 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 by mixing one or more solid metallic oxides with one or more binding agents and an expanding agent. The resulting product can be processed and the absorbent system regenerated. The carbon dioxide obtained in the process can be used as analytic or commercial carbonic gas, various carbamates and ammonium carbonate.
