Embodiment

[0027] If 100,000 hectares of barren hills, barren land, and tidal flats are used to plant 100,000 hectares, the annual output of Pennisetum per hectare is 60 tons of high-energy biomass (stalks), and the life span is 20 years as an example:

[0028] Annually, it can produce 6 million tons of high-energy biomass, produce 2.4 million tons of biocarbon, and capture 8.4 million tons of carbon dioxide, which is equivalent to capturing and storing all the carbon dioxide emitted by a large coal-fired power plant with an installed capacity of 1.2 million KVA a year. The lifespan of Pennisetum is calculated on the basis of 20 years, and 100,000 hectares of Pennisetum can capture 126 million tons of carbon dioxide in its lifetime, which is equivalent to the annual carbon dioxide emissions of 20 1 million KVA coal-fired power plants.

[0029] According to calculations by Tian Mu et al. (2009), the investment per kW of coal-fired power plants using ordinary carbon dioxide capture and stor...

Abstract

The invention discloses a production method, a storage method and a utilization method of pennisetum biochar. The production method comprises the steps of pennisetum cultivation, pennisetum harvesting, pennisetum pretreatment, and biochar production which is performed by preparing pretreated pennisetum stalks into the biochar with a smokeless coking technology; the storage method comprises a centralized storage method and an indirect storage method; the utilization method comprises two utilization manners of meliorating soil and serving as a strategic storage energy source; and the biochar is directly stored in soil, so that the purposes of meliorating the soil and improving photosynthesis efficiency of plants are achieved, and further, the pennisetum is promoted to capture and immobilize more carbon.

Description

technical field [0001] The invention relates to a production and storage method of pennisetum biological carbon and its utilization, a technology that can use pennisetum to capture and store carbon from the atmosphere, and belongs to the fields of biology, environmental protection and low-carbon technology. 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, or CSS for short, is the process of separating carbon dioxide from industrial and related energy sources, transporting it to a storage site, and keeping it sequestered from the atmosphere for long periods of time. At present, there are mainly four ways to capture and store carbon dioxide, namely, geological storage, ocean storage, conversion of carbon dioxide i...
