摘要/Abstract

摘要：

将2-甲基咪唑溶于乙二醇中形成混合溶液体系，利用该体系常温下实现对天然气中二氧化碳的脱除。首先分别测定单组分甲烷和二氧化碳在体系中的吸收容量，在0.1 MPa下，CO₂在2-甲基咪唑/乙二醇混合溶液中溶解度约为0.87 mol·L^-1，高于同等条件下CO₂在大部分离子液体中的溶解度，二氧化碳的吸收容量远大于甲烷的;然后对混合气CH₄/CO₂进行分离，发现该体系能较好吸收分离CH₄/CO₂。最后考察了体系的再生性和重复利用性，得出2-甲基咪唑/乙二醇溶液体系能完全再生并且能重复使用。

Abstract:

A binary liquid mixture system of 2-methylimidazole and ethylene glycol was used to remove carbon dioxide (CO₂) from natural gas at room temperature. The measurement on absorption capacity of methane (CH₄) and CO₂ in this system shows the CO₂ solubility about 0.87 mol·L^-1 at 0.1 MPa, which is higher than that in most ionic liquids under the same condition, and the absorption capacity of CO₂ was greater than that of CH₄. Further experimental results demonstrate that the liquid mixture could effectively separate CO₂/CH₄ gas mixture and could be regenerated and reused. After several cycles of absorption/desorption operations, the absorption capability was found barely changed, indicating good stability and application prospective of this binary system.

Key words: methane, carbon dioxide, ethylene glycol, 2-methylimidazole, absorption, separation, natural gas purification
