"Greenhouse effect" has been a serious threat to human survival and development. CO

sequestration as mineral carbonation is a potential carbon storage technology. In this paper

the feasibility of using albite and anorthite as the raw for CO

2

sequestration as mineral carbonation was studied from thermodynamics. The results showed that under a standard atmospheric pressure

the carbonation reaction of albite and anorthite could occur spontaneously when the reaction temperature was lower than about 75 ℃ and about 115 ℃ respectively. Under normal pressure

the carbonation conversion efficiency of albite and anorthite firstly maintaine

d 100% and then decreased sharply with the increase of reaction temperature. Under pressurized conditions

the suitable temperature range for mineral carbonation of albite and anorthite increased correspondingly with the increase of reaction pressure. In addition

when a reaction temperature was given

there would be an optimal reaction pressure point to make the influence of reaction pressure on the carbonation reaction maximum and the energy consumption minimum.
