Abstract: A method for reducing the risk of burning and explosion in a deoxygenation process of an oxygen-containing gas includes multiple steps. According to this method, in the presence of a gaseous alkane, hydrogen reacts with an oxygen-containing gas from which an unsaturated hydrocarbon has been removed.
