<p>A process for the extraction of carbon dioxide from a carbon dioxide-containing gas by calcium oxide by formation of calcium carbonate, said process comprising flowing said carbon dioxide-containing gas past or through a gas-porous, calcium oxide-containing ceramic member 1 disposed in a reactor vessel whereby said carbon dioxide-containing gas may permeate said member, and preferably subsequently heating said member and/or exposing said member to a gas having a lower carbon dioxide partial pressure than said carbon dioxide-containing gas whereby to cause calcium carbonate therein to release carbon dioxide, said member defining at least part of the inner wall of a gas flow conduit within said reactor vessel. Also disclosed are a conduit device, a process for the production of a ceramic product and a ceramic.</p> |
