摘要

"温室效应"已严重威胁着人类的生存和发展。矿物碳酸化封存CO

是一种极具潜力的碳封存技术。从热力学角度对钠长石和钙长石用于矿物碳酸化封存CO

的可行性进行了简单的研究。研究结果显示

在1个标准大气压条件下

当反应温度分别低于75℃左右和115℃左右时

钠长石和钙长石矿物碳酸化反应可以自发正方向进行;常压条件下

随着反应温度的升高

钠长石和钙长石矿物碳酸化转化效率均是先基本保持100%不变然后急剧降低;加压条件下

反应压力的增加

适合钠长石和钙长石矿物碳酸化反应的温度区间也会相应的增加;在给定的反应温度下

存在最佳的反应压力点

使得反应压力对矿物碳酸化反应的影响达到最大且能耗最小。

Abstract

"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

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.
