| Description | A large amount of COG (coke oven gas) is produced from coking plants every year, which contains 55–60% $H_{2}$. In this work, the breakthrough separation of $H_{2}$ from COG with ZIF-8/ethylene glycol-water slurry was studied. Following the investigation of the (ab-ad)sorption isotherms of the single component gas $CH_{4}$ and $H_{2}$, the main components of coke oven gas, in different slurries and their corresponding viscosities, and the influence of the operating conditions on the dynamic performance of $CH_{4}/H_{2}$ separation in slurry were studied in a bubble column. Low temperature, inlet flow rate, high pressure, and solid content can extend the breakthrough time, where the longest breakthrough time interval between $H_{2}$ and $CH_{4}$ can be as long as 70 min, meaning the high purity of $H_{2}$ product could be obtained easily. All the results of this work prove the feasibility of the slurry method to separate $CH_{4}/H_{2}$ mixture and provide a theoretical basis for practical industrial applications. |
