Abstract: The invention is a process and apparatus for eliminating most of the oxygen in a closed container by reacting the oxygen with carbon, such as carbon fibers, by electrically heating the carbon fibers until the carbon binds the oxygen into carbon dioxide, thereby removing the oxygen, and replacing the oxygen with carbon dioxide. This is important for preserving foods, certain plants, and other products which deteriorate in the presence of oxygen. The apparatus and process of the invention have significant economic value over the prior art.
