In this work, a systematic molecular simulation study was performed to compare the separation of CO2/N2 and CH4/N2 mixtures in two different classes nanoporous materials, zeolites, metal−organic frameworks (MOFs). For purpose, three zeolites (MFI, LTA, DDR) seven MOFs (Cu-BTC, MIL-47 (V), IRMOF-1, IRMOF-12, IRMOF-14, IRMOF-11, IRMOF-13) were chosen as representatives compare. On basis validated force fields, both adsorption selectivity pure CO2 CH4 isotherms simulated. The results show that...
In this work, molecular simulations were performed to evaluate the separation performance of two typical zeolitic imidazolate frameworks (ZIFs), ZIF-68 and ZIF-69, for CO2/N2, CO2/CH4, CH4/N2 mixtures. To do this, we first identified a suitable force field describing CO2, N2, CH4 adsorption in ZIFs. On basis validated field, selectivities three mixtures these ZIFs simulated then. The results show that ZIF-69 is more beneficial separating CO2 from CO2-related than ZIF-68, mainly due presence...
Abstract Removal of carbon dioxide is an essential step in many energy-related processes. Here we report a novel slurry concept that combines specific advantages metal-organic frameworks, ion liquids, amines and membranes by suspending zeolitic imidazolate framework-8 glycol-2-methylimidazole solution. We show this approach may give more efficient technology to capture compared conventional technologies. The sorption capacity our reaches 1.25 mol l −1 at 1 bar the selectivity...
The initial thickness of methane hydrate film was directly measured by suspending a single bubble in water at 274.0, 276.0, and 278.0 K. results show that the decreases from tens micrometers to about 10 µm with subcooling increased 0.5 K 3 When is higher than 1.0 K, all data under different temperatures vary inversely subcooling. Notable three‐dimensional growths crystals sizes shapes front emergence new crystal were clearly observed lower resulting rougher surface uncertainty measurement...
The kinetics of film growth hydrates methane, ethane and methane-ethane mixtures were studied by exposing a single gas bubble to water. morphologies, lateral rates thicknesses the hydrate films measured for various compositions degrees subcooling. A variety textures was revealed. two-dimensional inferred from rate initial thickness film. clear relationship between morphology observed. shape crystals found favour heat or mass transfer further quantitative results on showed that given degree...
In this work a systematic molecular simulation study was performed to the effect of interpenetration on gas mixture separation in metal−organic frameworks (MOFs). To do this, three pairs isoreticular MOFs (IRMOFs) with and without were adopted compare their adsorption selectivity for CH4/H2 mixtures at room temperature. The results show that methane is greatly enhanced interpenetrated IRMOFs compared noninterpenetrated counterparts, due formation additional small pores sites by frameworks....
This study investigated the occurrence of 12 veterinary antibiotics (VAs) and susceptibility Escherichia coli (E. coli) in a rural water system that was affected by livestock production northern China. Each surveyed sites determined with at least eight maximum concentration up to 450 ng L−1. The use VAs farming probably primary source rivers. Increasing total were measured from up- mid- downstream two tributaries. Eighty-eight percent 218 E. isolates derived area exhibited, total, 48...
