Problems solved by technology

[0006] 1. Carbon dioxide may escape from some stratum gaps, or even some abandoned mines, and re-enter the atmosphere;
[0007] 2. Carbon dioxide is very likely to leak from underground gaps and pollute groundwater;
[0008] 3. Once carbon dioxide diffuses and escapes into sedimentary layers or fractured rocks in the earth's crust, it is very likely to induce earthquakes;
[0009] 4. Even if carbon dioxide does not induce earthquakes through escape and diffusion, the carbon dioxide injected into the formation will not be evenly distributed due to the complexity of the geological structure of the gas reservoir, and the structural pressure formed in different regions will also be different; the reductio

Embodiment

[0030]Embodiment: A specific embodiment of the method for underground carbon sequestration using biomass in the present invention, crop stalks are selected as the biomass to be treated, and the specific treatment process includes: pre-drying the stalks to make the water content as much as possible Low, the drying process can be achieved by basking in the sun, so that the microorganisms will not be created with a water living environment, and it is also one of the necessary conditions for long-term storage of straw. Then crush the straw evenly, which is helpful to the subsequent compression molding, mainly to make the straw compressed evenly, and the compression density can also be controlled; if the whole straw is compressed, it will be loosened and loosened The place is dense and it is difficult to control the density, so it needs to be crushed. In addition, some viscose and preservatives are added for antiseptic treatment while the straw is crushed to further reduce the surv...

Embodiment approach

[0032] The first is to bury in situ near the raw material base. The advantage of this burial solution is that it reduces a lot of transportation costs. For this reason, when the dried, crushed and anti-corrosion treated straw is buried, it can be compacted while being buried. For example, a large pit is first dug near the raw material base, and the first batch of straw is laid in the pit, covered with soil and compacted. Then spread the second layer of straw and then cover with soil and tamp it tightly, and then repeat the above steps. During the burial process, the effect of compacting the straw is to reduce the contact surface between the biomass and the air, reduce oxidation, and prevent the growth of microorganisms; at the same time, it also saves the burial space, that is, saves the land.

[0033] Of course, there are also disadvantages in burying near the raw material base: the environment is relatively humid, and under too humid conditions, the biomass is easily decomp...

Abstract

The invention discloses a method for underground carbon storage by making use of biomass, which is characterized in that the biomass is dried in advance before being buried underground. The invention is that carbon dioxide is buried underground in a form biomass, and compression and anti-erosion treatments are continuously carried out on the biomass during the process to avoid the carbon dioxide being released caused by erosion. Obviously, the treatment method can suppress the discharge of carbon oxide on the earth from root, and save storage volume, relieve threaten to the crust and underground water by being compared with the existing liquid underground storage method of carbon oxide. The method of the invention is comparatively safe, with simple process and easy to perform, which is suitable for being prompted widely in environment-friendly enterprises.

Description

technical field [0001] The invention relates to a method for underground carbon fixation by using biomass, and belongs to the field related to solving the greenhouse effect of carbon dioxide in the environmental protection technology. Background technique [0002] The greenhouse effect of carbon dioxide is becoming more and more serious. In order to avoid the threat of climate warming, people have adopted policies and some measures to control carbon dioxide emissions or store carbon dioxide underground. But the current method has many deficiencies or drawbacks. [0003] First, through policies to reduce emissions, no matter how you reduce them, you are still emitting emissions. Recently, an American researcher said that even if people stop emitting carbon dioxide and other pollutants tomorrow, the situation of global warming will still be severe, not to mention reducing emissions. [0004] The second is to recover carbon dioxide from flue gas emitted by corporate factories...
