CO2 capture and storage (CCS) has been considered as one of the most effective strategies against global warming,among which sub-seabed CO2 storage in the form of gas hydrate is of great interest nowadays due to the large storage capacity of CO2 hydrate in the sub-seabed sediment and low risk of CO2 leakage.

作为特殊的地质流体,海底烃类物质的渗漏并形成天然气水合物的过程将会导致沉积物元素、微生物、自生矿物和碳酸盐岩地球化学等许多方面的异常,这些异常对海底浅表层天然气水合物的形成和产出具有直接或间接的指示作用,可以用来反演渗漏型天然气水合物的形成和保存条件.当然,这些矿物学和地球化学指标之间既有区别又有关联,需要因地制宜地给予分析和判别,包括矿物组成、元素含量和化学赋存状态、微生物作用等多方面的综合研究
冷泉系统中的CH4 主要通过对流和扩散的方式向海底运移,在运移至浅表层沉积物中,CH4 会与海水中向下扩散的SO42-发生甲烷缺氧氧化作用(AOM),转化为溶解无机碳(DIC).一部分DIC 通过自生碳酸盐矿物的沉淀被消耗,剩余的可能继续向海底运移进入水体.此外,海底浅层沉积物中的有机质氧化和硫酸盐还原作用(OSR)也是DIC通量的主要贡献值之一.海底界面的CH4 和DIC 通量对于海水CO2 乃
Multi-beam and pusdo-3D subbottom profile surveys were conducted to identify the fractures and faults on seafloor or sub-seafloor on Gas Hydrate Production Test (GHPT) site in the Ulleung Basin,East S
Steel production process using fossil fuels is a large source of CO2 emission,and thus various technologies to separate CO2 from the exhaust gas of the steel production process have been investigated.
The separation of CO2 based on clathrate hydrates formation was considered as a promising technology and potentially economically competitive comparing to the conventional processes.
In this study,the feasibility of hydrate-based precombustion CO2 capture in the presence of thermodynamic promoters was investigated with a primary focus on stability condition measurements and micros
As a new potential alternative source of energy in 21st century,gas hydrate has been studied wide on gas hydrate occurrence,lithology particle size,porosity,permeability of sediment bearing gas hydrat
The post-combustion CO2 capture by using clathrates is a method which takes profit of the CO2 selectivity in gas hydrate to separate it from nitrogen,or other exhausting gases from gas combustion or c
Quaternary ammonium salts (QASs) form semiclathrate hydrates under higher temperature and lower pressure conditions when compared with gas hydrates.
The CO2 capture by using clathrates is a method which takes profit of the CO2 selectivity in gas hydrate to separate it from nitrogen,or other exhausting gases from gas combustion or coal combustion.T
