Problems solved by technology

Carbon capture and storage (CCS for short) refers to the process of separating carbon dioxide from industrial and related energy sources, transporting it to a storage location, and keeping it isolated from the atmosphere for a long time; currently there are four main ways to capture and store carbon dioxide, namely geological storage, marine seque

Embodiment

[0016] A. For the cultivation of Miscanthus plants, choose floodplains, barren hills and tidal flats that are close to water sources or with abundant rainfall. After plowing and raking the ground, excavate planting holes, 15,000 holes per hectare, the hole depth is 8-12cm, preferably about 10cm, and the inside is 5-10cm, preferably about 7cm, which has been stacked with mature organic fertilizer and soil mixture, and then plant the seedlings Put in, cover soil 3-7cm, preferably about 5cm, watered and soaked, and can be planted from March to October.

[0017] B. Harvesting of miscanthus plants. Miscanthus plants grow until November of the next year, the leaves begin to turn yellow and dry, and the nutrients in the leaves and stems above the ground return to the underground part; after the leaves are completely dry, they can be harvested with a special harvester ; In order to reduce the moisture content of the stalks during pretreatment, it can be air-dried in the field ...

Abstract

The invention relates to a method for preparing biological carbon used for capturing and storing carbon dioxide in the air from miscanthus, comprising the following steps: culturing the miscanthus, harvesting the miscanthus, preprocessing the miscanthus and producing the biological carbon. In the step of processing the miscanthus, the stalks of the harvested miscanthus are air-dried and cut into segments with certain length so as to be suitable for smokeless coking process, and then the stalks of the processed miscanthus are produced into the biological carbon at high temperature of 400-700 DEG C in the absence of oxygen by the smokeless coking process. The biological carbon storage methods comprise a centralized biological carbon storage method and an indirect biological carbon storage method. The biological carbon can be used for soil reclamation or as strategic reserve energy. The biological carbon can be used for economically and efficiently capturing and storing the carbon dioxide in the air without causing pollution to environment.

Description

technical field [0001] The present invention relates to a technique for developing and utilizing barren hills, barren land, and barren beaches to plant Miscanthus plants, and then prepare and store biological carbon through said Miscanthus plants, so as to capture and store carbon dioxide in the atmosphere. It belongs to biology, Environmental protection and low-carbon technology fields. Background technique [0002] In recent years, with the frequent occurrence of abnormal climates, people have focused their attention on global climate change, and more and more evidences have proved that the increase of carbon dioxide concentration is the main cause of global warming. Carbon capture and storage (CCS for short) refers to the process of separating carbon dioxide from industrial and related energy sources, transporting it to a storage location, and keeping it isolated from the atmosphere for a long time; currently there are four main ways to capture and store carbon di...
