Problems solved by technology

This chemical fixation of carbon effectively reduces the amount of carbon dioxide emitted into the atmosphere, but since the amount of carbon dioxide consumed by these synthetic products is insignificant compared to the 20 billion tons emitted into the atmosphere every year
[0008] In addition, some people propose to store carbon dioxide in the deep sea or abandoned mines. This idea treats carbon dioxide as a pure pollutant and does not treat it as a resource. reuse problem

Embodiment 1

[0036] Embodiment 1 (variable metal oxide reduction method)

[0037] The carbon dioxide produced by fuel combustion reacts with the low-valent oxides of variable-valent metals in the reactor, carbon dioxide is reduced to carbon monoxide, and low-valent metal oxides are oxidized to high-valent metal oxides. The reaction formula is as follows:

[0038] MeO+CO 2 = Me 2 o 3 +CO

[0039] In the formula: Me represents metal

[0040] Carbon monoxide or carbon, which is reduced to carbon dioxide, is burned to release heat energy, which is oxidized to carbon dioxide. The oxidized high-valent metal oxides are reduced to low-valent metal oxides with hydrogen, and the reaction formula is as follows:

[0041] CO+1 / 2O 2 =CO 2

[0042] Me 2 o 3 +H 2 =MeO+H 2 o

[0043] The reducing agent hydrogen used is produced by the electrolysis of water from cheap energy sources (such as: solar energy).

[0044] The nascent carbon dioxide reacts with low-priced metal oxides to form carbon ...

Embodiment 2

[0045] Embodiment 2 (metal reduction method)

[0046] In the reactor, carbon dioxide reacts with metal, carbon dioxide is reduced to carbon monoxide or carbon, metal is oxidized to metal oxide, the reaction formula is as follows:

[0047] Me+CO 2 =MeO+CO

[0048] 2Me+CO 2 =2MeO+C

[0049] Carbon monoxide or carbon, which is reduced to carbon dioxide, is burned to release heat energy, which is oxidized to carbon dioxide. The oxidized metal oxide is reduced to metal with hydrogen, and the reaction formula is as follows:

[0050] CO+1 / 2O2 =CO 2

[0051] C+O 2 =CO 2

[0052] MeO+H 2 =Me+H 2 o

[0053] The nascent carbon dioxide reacts with metals to form carbon monoxide and metal oxides again. This cycle continues repeatedly, transforming inconvenient and cheap energy into heat energy that people are used to, greatly reducing the consumption of fossil fuels, that is, reducing carbon dioxide emissions.

Abstract

The invention belongs to the environment protection field, in particular to a recycling technology of converting carbon dioxide to carbon monoxide, and aims to reduce fossil fuel consumption and the carbon dioxide amount discharged into atmosphere. The technology is as follows: carbon dioxide produced by fuel combustion is reduced to carbon or carbon monoxide which can burned; newly produced carbon or carbon monoxide is burned to release energy, so as to form the recycling of carbon and reduce fuel consumption, that is, reducing the discharge amount of carbon dioxide. By adopting the technical means, required consumed energy is converted to heat energy which is commonly used by people through cheap energy source, such as solar energy, so as to complete the energy conversion process. The technology realizes the recycling of carbon through the reduction of carbon dioxide, thereby greatly reducing the consumption of fossil fuel.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a technology for recycling carbon dioxide, an air pollutant, thereby reducing the consumption of fossil fuels and the amount of carbon dioxide discharged into the atmosphere. Background technique [0002] Due to the development of industry, a large number of fossil fuel resources such as coal, oil, and natural gas have been exploited. While they are continuously consumed as energy sources, CO in the atmosphere 2 content is increasing day by day. The amount of carbon dioxide emitted by the world every year is as high as 20 billion tons. so much CO 2 Despite continuous uptake by plants, atmospheric CO 2 content is still increasing. The continuous increase of the concentration of carbon dioxide in the atmosphere will firstly intensify the "greenhouse effect", secondly, the ecological balance will be severely damaged, causing a series of ecological environmental ...
