The invention discloses a device and a method for converting carbon dioxide into carbon monoxide, and relates to the technical field of chemical basic raw materials. The device comprises a water decomposition and hydrogen production device and a hydrogenation reaction device, wherein the water decomposition and hydrogen production device is connected with a water pipe; hydrogen produced by the water decomposition and hydrogen production device and carbon dioxide are conveyed into the hydrogenation reaction device respectively through pines; the hydrogenation reaction device is connected with a water cooler; the water cooler is connected with a gas-liquid separator. The hydrogen produced by the water decomposition and hydrogen production device and the external carbon dioxide are conveyed into the hydrogenation reaction device respectively, and a carbon-hydrogen ratio of CO2 to H2 is regulated to be 1 to 1 under the conditions that the temperature is greater than or equal to 250 DEG C and the pressure is 0.1MPa to 1.0MPa; a reaction resultant CO and H2O are cooled through the water cooler, and reaction water and the CO are separated out through the gas-liquid separator; the reaction water can be circularly utilized, and the CO is used as a product. By adopting the device and the method, disclosed by the invention, the hydrogen production cost can be reduced, and the economical efficiency of converting the CO2 into the CO is improved.
Description
technical field [0001] The invention relates to the technical field of basic chemical raw materials, in particular to a device and method for converting carbon dioxide into carbon monoxide. Background technique [0002] Energy is the basis for human survival, and it plays a very important role in human development. With the rapid development of economy, human demand for energy is increasing. The energy we use mainly comes from oil, coal and natural gas, which together account for more than 85% of the total energy used in the world today. However, the reserves of fossil fuels are far from meeting the needs of people's production and life, so renewable energy must be developed. Renewable energy includes solar energy, wind energy, tidal energy, etc. They are not only rich in reserves, but also do not cause environmental pollution, and are an efficient and clean energy source. At present, they are mainly used to generate electricity. However, due to the restrictions of season...
