Description
Technical Field
The invention relates to the technical field of carbon dioxide sequestration, in particular to forsterite-based foamed ceramic for carbon sequestration and a preparation method thereof.
Background
With the continuous development of human industrial activities, the concentration of carbon dioxide in the atmosphere is gradually increased, so that the problems of extreme weather, sea level rise, species extinction, ecological system deterioration and the like occur in the world, and the future life safety of human beings is seriously threatened. There is a need to find effective and low cost carbon abatement solutions and to actively advance carbon dioxide capture and sequestration (CCS) technologies. The carbon sequestration is the core of the technology and mainly comprises geological sequestration, ocean sequestration and mineral sequestration. Compared with the prior art, the mineral sealing and storing technology has the characteristics of environmental protection, safety, permanence and the like, and the carbon dioxide mineral sealing and storing raw material has rich sources, huge reserves and low price, and has large-scale carbon sealing and storing potential and good economic benefit.
Among common mineral sealing raw materials, forsterite is the only stable refractory phase in a MgO-SiO2 binary system, has higher theoretical carbon sealing amount, is rich in reserves in China, and is a mineral resource for carbon dioxide sealing with great potential. In the conventional carbon sequestration process, in order to increase the carbonization reaction rate, forsterite is usually processed into powder, and then modified and subjected to subsequent heat treatment to finally obtain the reactant powder containing carbonate. The accumulated cost of the reactant powder is increased due to the problems of subsequent storage, transportation, recycling and the like, and the process is not favorable for industrial popularization and application.
With the development of the technology, in order to improve the reutilization rate of the forsterite mineralization reaction product and reduce the industrial production cost, a new process is provided, and the forsterite can be prepared into foamed ceramics with low density, high strength, high specific surface area and high adsorbability, so that the comprehensive utilization rate of resources is improved while the carbon sequestration rate of the forsterite is not reduced. In the preparation process of the foamed ceramics, the organic foam impregnation method has the advantages of simple process flow, controllable pore structure, lower cost and the like, and is most widely applied to industrial production. However, in the heat treatment process, the ceramic pore ribs have hollow structures due to the loss of the organic template, so that the mechanical property, the thermal shock resistance and the like of the ceramic pore ribs are damaged. So far, a contradiction arises in the process of the forsterite-based foamed ceramic, and the number of internal holes needs to be increased in order to improve the adsorption performance, and the number of internal holes needs to be reduced in order to improve the strength of the whole structure. In addition, the magnesium oxide ceramic itself is far inferior to the alumina ceramic in physical parameters such as tensile strength, compressive strength and bending strength, so that it is difficult to balance the carbon dioxide absorption efficiency and the structural strength of the forsterite-based ceramic foam for carbon neutralization.
