Embodiment 1

[0013] The carbon dioxide exhaust gas discharged from power plants, iron and steel factories, etc. is filtered to remove mechanical impurities, and then sulfur oxides are removed through a calcium hydroxide aqueous solution (20-30% by weight concentration), and the catalyst antimony oxide (attached to the carbon nanotube carrier) In the presence of (above), react at 340° C., separate and purify to remove nitrogen oxides, and obtain carbon dioxide gas with a purity of 95%. Wherein the catalyst in this step is preferably a nanometer catalyst, that is, the particle size of the catalyst should be between 0.1 and 100 nanometers.

[0014] Then measured by the flow meter, pressurize the carbon dioxide gas to 5kg / cm according to the required mole ratio 2 Finally, enter the horizontal reactor with an inner diameter of 5 feet and a length of 40 feet, and control the flow rate of carbon dioxide gas to be 2 m / s. The flow rate of carbon dioxide gas should be adjusted accordingly according...

Embodiment 2

[0019] The carbon dioxide waste gas discharged from power plants, iron and steel factories, etc., is subjected to the separation and filtration treatment steps in Example 1 to obtain carbon dioxide gas with a purity of 80%.

[0020] Then measured by the flow meter, pressurize the carbon dioxide gas to 5kg / cm according to the required mole ratio 2 Finally, enter the horizontal reactor with an inner diameter of 5 feet and a length of 40 feet, and control the flow rate of carbon dioxide gas to be 2 m / s. While carbon dioxide and carbon nanotubes undergo a reduction reaction to generate carbon monoxide, the water measured by the flow meter is pressurized to 5kg / cm according to the required molar ratio. 2 After that, water mist is formed in the reaction through the nozzle.

[0021] The mole ratio of carbon dioxide, water and carbon is 70:7:9, that is, carbon dioxide is 15.7M 3 , 1260ml of water and 1.08kg of carbon nanotubes. At a reaction temperature of 900°C and a pressure of 5...

Abstract

A method for preparing synthesis gas, comprising: introducing the compressed carbon dioxide to the reactor containing catalyst and catalyst carrier, introducing the compressed water to the reactor to produce synthesis gas under the catalysis effect by catalyst. The invention is characterized in that the reaction temperature is 700-1500 DEG C, pressure is 1~90 kg / cm2, the catalyst carrier is carbon nanometer tube, carbon tube containing carbon powder in nanometer class or not in nanometer calss. The catalyst in this invention makes the material handling more convenient and it is easier to realize automatic production. The purity of methane in the generated gas is dramatically improved and the safety in the process is also improved dramatically.

Description

【Field of Invention】 [0001] The invention relates to a method for producing gas, in particular to a method for preparing synthetic gas by utilizing the reaction of carbon dioxide, carbon and water. 【Background technique】 [0002] The development of the economy must rely on industry, and the development of some industries is inseparable from electricity. All kinds of industrial production and part of electricity use natural energy such as natural gas, coal, oil, etc. as fuel. As a result of combustion, a large amount of carbon dioxide waste gas is produced, and its emission has caused serious pollution to the earth, and has even produced a greenhouse effect. Carbon dioxide waste gas is a great source of pollution. From the perspective of environmental protection, sometimes a large expenditure must be invested to offset the loss caused by carbon dioxide waste gas. For example, according to the report of the British Economist in October 1999: American Electric Power Company an...
