Problems solved by technology
Among them: physical pressure swing adsorption deoxygenation and chemical adsorption deoxidation load are small, and the deoxidation effect is poor; activated carbon combustion deoxygenation temperature is high, and energy consumption is high; most of the catalytic combustion deoxygenation technology needs to add reducing gases such as H 2
However, the current catalytic oxidation deoxygenation technology is mainly aimed at the removal of oxygen in methane-containing gases such as coalbed methane and landfill gas. The oxygen content in unsaturated hydrocarbon gas is relatively high, such as when the oxygen content is 0.2%-12wt%, the deoxygenation effect is not good

Description
technical field [0001] The invention relates to the technical field of deoxygenation, in particular to a deoxygenation device for unsaturated hydrocarbon gas. Background technique [0002] Oxygen-containing organic hydrocarbon gas is a common gas in the process of chemical production, storage and transportation at present. Taking unsaturated hydrocarbon gas containing oxygen as an example, it often brings the risk of explosion due to the high oxygen content. Therefore, in order to reduce the risk of explosion, recycle oxygen-containing organic hydrocarbon gases, and ensure that oxygen-containing organic hydrocarbon gases meet emission requirements, it is necessary to perform deoxygenation treatment on oxygen-containing organic hydrocarbon gases to reduce the oxygen content. [0003] At present, deoxygenation technologies mainly include physical pressure swing adsorption deoxygenation, chemical adsorption deoxidation, activated carbon combustion deoxygenation, catalytic combu...
