Abstract

Abstract:

In order to capture methane effectively from coke oven gas and coalbed methane, this paper proposes a new capture technology: absorption-adsorption combined method to capture methane by suspending ZIF-8 (zeolitic imidazolate framework-8) in a glycol-water solution. Firstly, the absorption-adsorption capacities of methane, nitrogen and hydrogen in the slurry were measured. The order of adsorption capacities were CH₄> N₂> H₂. Then the ability of separation of the slurry for the mixtures of CH₄/H₂ and CH₄/N₂were investigated. It was found that the mixtures can be separated effectively. The recovered ZIF-8 from the slurry was analyzed using XRD, and the results demonstrated that ZIF-8 did not change throughout the separation process and ZIF-8/glycol-water slurry can be reused.

Key words: ZIF-8, glycol-water solution, CH₄, absorption-adsorption, equilibrium

摘要：

为了有效地捕集焦炉气及煤层气中的甲烷,提出了一种新型捕集技术:吸收-吸附组合方法,该方法通过把ZIF-8分散到乙二醇水溶液中形成悬浮浆液,实现对甲烷组分的捕集。首先测定了甲烷、氮气和氢气在浆液中的吸收-吸附容量,得出吸着量大小的顺序为CH₄> N₂> H₂,然后对CH₄/H₂和CH₄/N₂的混合气进行吸着平衡研究,发现浆液均能有选择性地吸着甲烷。对浆液中回收的ZIF-8材料进行XRD表征,分析证明在整个吸着过程中ZIF-8结构没有发生变化并且ZIF-8/乙二醇-水浆液能重复利用。
