The chemical equation for the reaction of removing carbon dioxide from carbon monoxide

Method 1: Sodium hydroxide is passed into the gas mixture.

solution (similar to KOH solution), the reaction principle is:

CO2 + 2NaOH = = Na2CO3 + H2O Method 2: Through the red-hot carbon layer, the reaction principle is: CO2 + C (high temperature) = 2CO

Due to the high reaction conditions with the hot carbon layer, high temperature is required, which is not convenient enough. It is convenient to introduce sodium hydroxide solution.

Note: Clarified lime water cannot be passed because of calcium hydroxide.

Slightly soluble in water, the solution concentration is low, and it will cause carbon dioxide.

There are two ways to do this. 1.Pass an excess of a highly concentrated NaOH or KOH solution. 2.Co-heating with excess C high temperature to go out CO2.

The equation for carbon dioxide to carbon monoxide is: CO2 + C = 2CO (high temperature); CO2 + H2 = CO + H2O (high temperature).

Analysis: Carbon dioxide itself does not support combustion, but it reacts with some reactive metals under ignition conditions to produce oxides and carbon monoxide of the corresponding metals. At high temperatures, carbon dioxide can be reduced by carbon to form carbon monoxide.

Chemical properties of carbon dioxide:

Carbon dioxide is one of the carbons, which is an inorganic substance, is non-flammable, does not usually support combustion, and is non-toxic at low concentrations.

It is also the anhydride of carbonic acid, which belongs to acidic oxides, and has the universality of acidic oxides, in which the valency of carbon is 4 valence, which is in the most advanced state of carbon elements, so carbon dioxide has oxidation and no reduction, but the oxidation is not strong.

Carbon dioxide. It does not support combustion, but it reacts with some reactive metals under ignition conditions to produce oxides and carbon monoxide of the corresponding metals.

At high temperatures, carbon dioxide can be reduced by carbon to form carbon monoxide.

Carbon monoxide is a combustible gas, which becomes carbon dioxide when burned, that is, carbon monoxide reacts with oxygen to produce carbon dioxide.

Chemical equation.

2CO+O2=ignite 2CO2 or use carbon monoxide and oxonated copper.

The reaction produces carbon dioxide and copper.

The chemical equation is CO+CuO=heating CO2+Cu carbon dioxide plus carbon monoxide under high temperature conditions, and the chemical equation is CO2+C=high temperature 2CO.

Carbon reduces carbon dioxide.

The chemical equation is the redox reaction.

In the reaction, carbon acts as a reducing agent, reducing carbon dioxide. Carbon and carbon dioxide react at high temperatures to form carbon monoxide, and the equation is: C+CO = 2CO (high temperature).

Carbon is a non-metallic element, with the chemical symbol C, which has stability at room temperature, is not reactive, has very low toxicity to the human body, and can even be safely ingested in the form of graphite or activated carbon, located on the periodic table.

1. Carbon and carbon dioxide.

It reacts at high temperatures to produce carbon monoxide.

The equation is as follows: C+CO=2CO (high temperature).

2. Carbon dioxide gas is a part of the composition of the atmosphere (accounting for about the total volume of the atmosphere, which is abundant in nature, and its production methods are mainly as follows: organic matter (including animals and plants) can release carbon dioxide in the process of decomposition, fermentation, decay and deterioration. Carbon dioxide is also released during the combustion of oil, paraffin, coal, and natural gas.

Petroleum and coal also release carbon dioxide in the production of chemical products. All feces, humic acid.

In the process of fermentation and maturation, carbon dioxide can also be released. All animals breathe oxygen and exhale carbon dioxide during the respiration process.

The chemical equation for converting carbon monoxide to carbon dioxide is CO+O2 CO2.

1. Basic introduction to carbon monoxide and carbon dioxide

Carbon monoxide (CO) and carbon dioxide (CO2) are both molecules made up of the elements carbon and oxygen. And the most significant difference between the two is their oxidation state: in the carbon monoxide molecule, the oxidation state of the carbon atom is +2, while in carbon dioxide it is +4.

2. Chemical equations

1. The chemical equation for the conversion of carbon monoxide to carbon dioxide is as follows: CO+O2 CO2 This reaction usually requires temperature and catalyst to occur. The use of copper catalysts is one of the most commonly used methods for most laboratory extensions.

2. Specifically, the reaction involved in the removal of CO in air requires a temperature of up to 280-350 °C, and with the action of a suitable copper catalyst, this temperature can be reduced to about 180 °C.

3. Carbon monoxide

1. Carbon monoxide is a colorless, odorless, and odorless gas, but it can combine with hemoglobin and form carboxyhemoglobin (carbon monoxide hemoglobin) in the human body, which can lead to hypoxia and death.

2. Despite its high toxicity, carbon monoxide can have very practical characteristics in some cases. For example, it can be used as a reaction intermediate for organic substances such as isoalkanes and fatty acids to produce methane, hydrocarbons, and other practical materials.

3. Carbon monoxide can also be converted into methanol through a reaction path called the "Fisher-Troppush reaction", which is very important because it is one of the prerequisites for the preparation of some important compounds.

Fourth, carbon dioxide

1. Carbon dioxide is a molecule that coexists and circulates in nature, which can be inhaled into the atmosphere by plants, and converted into substances originating from hydrogen, carbon and oxygen through photosynthesis until it is converted into oxygen and carbohydrates.

2. At present, the concentration of carbon dioxide in the earth's atmosphere is continuing to rise, and Dajingji is one of the important factors of global climate change. In order to prevent and control global climate change, different countries and regions have taken measures such as limiting emissions and building low-carbon cities.

3. Carbon monoxide and carbon dioxide are two very important molecules, and they play an irreplaceable role in many fields. In terms of understanding the properties and characteristics of these molecules, chemical equations can help us better understand the reaction processes between them and the various practical chemical rolling reactions in which they are involved.

To remove carbon dioxide from carbon monoxide, according to the principle of removing impurities and not adding impurities, two methods are usually used:

1. Pass in a sufficient amount of clarified lime water

CO2 + Ca(OH)2CaCO3 + H2O, CaCO3 is the precipitate;

2 Through the searing carbon layer:

C + CO2 2Co, reaction conditions high temperature.
