A method of converting carbon dioxide into a chemical energy substance

Abstract

The invention discloses a CO 2 Be converted into the method for chemical energy substance, it comprises the following steps: (1) under electric field effect, CO 2 The gas is broken down and discharged to form high-temperature CO with a temperature of 2000-5000K 2 plasma jet; the CO 2 Plasma includes uncracked CO 2 and CO 2 CO, O, O produced by cracking 2 ; (2) step (1) gained CO 2 Plasma jets further decompose CO in a fixed-bed reactor 2 Conversion to CO; the fixed bed reactor is packed with carbonaceous material or alumina particles. Very ingeniously, the present invention utilizes high temperature CO 2 The high-temperature environment of the plasma jet makes the carbon-containing substances quickly devour the oxygen in the cracked gas, and at the same time, the carbon-containing substances and uncracked CO are used 2 The reaction is converted to CO, making full use of CO 2 The thermal energy carried by the plasma jet quickly reduces the temperature, which effectively avoids the reverse reaction from the two opposite sides of lowering the temperature and reducing the oxygen element, realizes stable CO production, and greatly improves the CO production. 2 Conversion rate and power usage efficiency.

Description

technical field [0001] The present invention relates to a CO 2 A method of converting into chemical energy substances. Background technique [0002] With the continuous use of fossil energy (oil, natural gas and coal), it inevitably brings two serious problems. One is the energy crisis caused by the gradual reduction of reserves of fossil energy due to the non-renewability of fossil energy, and the other is that the extensive use of fossil energy leads to the increasing concentration of carbon dioxide in the atmosphere and causes the greenhouse effect. Therefore, sustainable energy, such as solar energy, nuclear energy, water energy, wind energy, etc. will become the main energy source in the future. However, this kind of energy is physical energy, which is usually obtained in the form of electric energy, which not only has time and space limitations in supply, but also cannot meet the needs of human society for hydrocarbon chemical raw materials. [0003] In order to sol...

Problems solved by technology

Although the two technologies have been industrialized, both rely on the heat generated by burning carbonaceous substances to drive chemical reactions, which not only produce a large amount of CO 2 emissions, increasing the environmental load, and it is impossible to achieve CO 2 The ultimate goal of reducing emissions and converting renewable electrical energy into chemical energy

CO under development 2 Catalytic reforming of methane technology also converts CO 2 , but this process has not been broken through for a long time because it is difficult to overcome the deactivation of carbon on the catalyst surface

Cracking of CO by low-temperature non-equilibrium plasma under development 2 Technologies, such as slip arc plasma and dielectric barrier plasma technology, rely entirely on high-energy electrons colliding with CO 2 If it is cracked, it is difficult for the cracked gas to react with carbon-containing substances, and there are problems such as low reaction conversion rate, large power consumption, and difficulty in expanding production capacity.
