多类型岩石二氧化碳矿化封存机制研究
Study of CO2 mineralization and storage mechanism in basalt and sandstone
摘要
Abstract
Anthropogenic emissions of CO2 pose a serious threat to the human living environment and lead to sig-nificant changes in the ecosystem.Geological storage,which has been proposed in recent years as one of the tech-nologies to deal with excess CO2 in the atmosphere,can be categorized into physical storage,which relies on the physical properties of the pores of the reservoir rock,and chemical storage,which is realized through the reaction of CO2 with the surrounding rocks.The chemical method of mineralized storage utilizes the process of converting CO2 into stable solid carbonates to achieve the goal of long-term storage,which is regarded as the safest and most stable storage technology.By discussing the principle and potential of CO2 mineralization,we comparatively ana-lyzed the reaction mechanisms,influencing factors,mineralization rates,and storage capacities in different rocks,and summarized the advantages and disadvantages of CO2 mineralization in basalt and sandstone.Combined with two basalt mineralization demonstration projects that have been successfully implemented globally at present,we put forward the ideas and prospects for CO2 mineralization and storage in clastic rock reservoirs.关键词
