The mass percentage concentration of the alkali liquor is 1 to 40 percent. The reaction temperature is between 0 and 60 DEG C. The reaction pressure is between 0.01 and 1 MPa.
Description
Technical field
The present invention relates to a kind of method of catching carbon dioxide, be specifically related to a kind of with chemical reaction with carbon dioxide (CO
2) method of catching.
Background technology
In atmospheric environment, have multiple chemical substance, under general situation, can not impact ecology, but industrial expansion uses the various industrialization machineries and the vehicles recently, and the chemical substance of being discharged is more and more, the concentration of discharging exceeds standard, causes environmental pollution.
It is the most valued at present environmental protection problem that terrestrial climate warms.The atmospheric gas that greenhouse gases can cause temperature of the earth to rise, topmost greenhouse gases are carbon dioxide, methane and nitrogen dioxide etc., especially carbon dioxide in the atmosphere.
Mankind's activity causes great amount of carbon dioxide discharging, has caused huge ambient influnence, and global emission amount of carbon dioxide is just with annual 3% speed increment, and the climate warming problem is more and more severeer.
Current, carbon dioxide capture with seal technology up for safekeeping, be regarded as tackling one of most important technology of Global climate change in a short time, be divided into seizure, transport and seal up for safekeeping three links.For carbon dioxide capture, three kinds of methods having grasped at present are to catch and the oxygen-enriched combusting seizure before catching after the burning, burning.The mode of sealing up for safekeeping of carbon dioxide is divided into four kinds, and the one, by chemical reaction carbon dioxide is changed into solid inorganic carbonate; The 2nd, commercial Application, direct raw materials for production as multiple carbon containing chemicals; The 3rd, inject the depths of ocean below 1000 meters; The 4th, inject subterranean strata.
Carbon dioxide capture is still under test with the technology of sealing up for safekeeping at present, and technical immature and expensive this technology that causes is difficult to large-scale popularization.According to estimates, catch and the cost of handling carbon dioxide probably at 75～115 dollars/ton, compare with the price of new forms of energy such as exploitation wind energy, solar energy and not have too big competitive advantage.(today science and technology, 2009,12,42)
Therefore, the new technology of exploitation catching carbon dioxide technology is important topic (Wang, a C.; Luo, H.; Jiang, D.; Li, H.; Dai, S.Angew.Chem.Int.Ed.2010,49,5978).
