Methanol Reforming Reactor for Selective Oxidation and Purification of CO

Abstract

The invention relates to a selective CO oxidative purification methanol reforming reactor. The selective CO oxidative purification methanol reforming reactor comprises a reforming reaction chamber and at least one CO purification reactor used for reducing CO in hydrogen-rich gases generated by reforming reaction, wherein each CO purification reactor is at least provided with an input port and an output port; the input ports are connected with a reforming synthesis gas output port of the reforming reaction chamber; the output ports are used for outputting purified hydrogen-rich gases; each CO purification reactor is at least provided with an oxygen or air input pipe, and a catalyst filling body for selective oxidative CO reaction is arranged in each CO purification reactor. By adoption of selective CO oxidative purification, the content of CO in the hydrogen-rich gases generated in the reforming reaction chamber can be effectively reduced. The reforming reaction chamber and the CO purification reactors adopt an integrated design, so that the weight is further reduced, and the structure is compact. The methanol reforming reactor is mainly used together with a proton-exchange membrane fuel cell and used for providing hydrogen for the proton-exchange membrane fuel cell.

Description

technical field [0001] The invention relates to the technical field of hydrogen production by reforming, in particular to a reaction device for producing hydrogen by reforming methanol and purifying CO in hydrogen-rich gas obtained by the reforming reaction. Background technique [0002] Among the many new energy sources, hydrogen energy will become the most ideal energy source in the 21st century. In the case of burning the same coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water, without ash and waste gas, and will not pollute the environment. [0003] Proton exchange membrane fuel cells (PEMFC) need pure hydrogen as fuel, but the transportation, storage, filling technology and facilities of pure hydrogen cannot meet the requirements of distributed power plants, especially for household use, so through the existing fossil fuel storage It has become an international general method to use fuel reforming to produce hydro...
