Separation of IGCC syngas by using ZIF-8/dimethylacetamide slurry with high CO2 sorption capacity and sorption speed but low sorption heat

Facilely Cross-Linking Polybenzimidazole with Polycarboxylic Acids to Improve H2/CO2 Separation Performance

“…Gas sorption ( C A , cm 3 (STP) cm –3 ) at a constant pressure ( p A , atm) for glassy polymers is often described using the dual-mode sorption model , where k D is Henry’s constant, C ′ H is Langmuir sorption capacity, and b is the affinity parameter. The PBI’s CO 2 sorption in this study is slightly lower than those reported in the literature, presumably due to the different processing conditions. ,,, The sorption isotherms can be satisfactorily described using this model with the values of the adjustable parameters recorded in Table S2.…”

PBI-TaA 0.32 and PBI-OA 0.49 show almost the same CO 2 and C 2 H 6 sorption (cf.…”

Separation of butane isomers using a novel ZIF-8 slurry with extremely high efficiency: from laboratory study to industrial pilot test

“…10. As shown in our previous reports 32,37 , there are two main components, a stainless steel blind cell with 132.4 cm 3 effective volume (including the connected pipeline) and a transparent sapphire cell with 59.9 cm 3 effective volume (including the connected pipeline), both are installed in a constant temperature air bath to keep the uniform temperature. The maximum working pressure of two cells are designed to be 20 MPa.…”

“…Li et al 33 successfully run the ZIF-8 slurry in a pilot-scale packed tower for CO2 capture and achieved good results in the aspects of separation efficiency, energy consumption, and stability during slurry operation. Pan et al 34 , Liu et al 35 , Chen et al 36 ,Yang et al 37 have applied this method to the separation of a series of low boiling gas mixtures like natural gases, FCC dry gases, coal bed gases, IGCC syngas etc. They all achieved promising results.…”

Experimental Study on Breakthrough Separation for Hydrogen Recovery from Coke Oven Gas Using ZIF-8 Slurry

“…Liu et al [21] proposed a ZIF-8/glycol-water slurry absorptionadsorption hybrid method to separate the gas mixture, where ZIF-8 can be suspended in water and maintain its adsorption performance because of its hydrophobicity and the similar density to water. By experiments, the solubility and separation performance of the slurry for carbon dioxide [22,23], low-boiling hydrocarbon [21], and their mixtures [24,25] were studied, and a continuous (ab-ad)sorption-desorption process was proposed with its mathematical model also developed [26]. Furthermore, the (ab-ad)sorption-desorption process was successfully run in a pilot-scale plant with promising results [27,28].…”
