In this paper, we report N 2 , CH 4 and CO 2 adsorption in single-walled silicon carbon nanotubes (SiCNTs) using grand canonical Monte-Carlo and calculate the isosteric heat of gas adsorption. The results demonstrate that at ambient temperature and high pressure, gas adsorption in these nanotubes is in the order of CO 2 [ CH 4 [ N 2 and nanotubes' order is (10,10) \ (20,20) \ (40,40), while this order of adsorptivity of nanotubes will be inverted for N 2 when the pressure is very low. Then, we fit our simulation results to Langmuir and Langmuir-Freundlich equations to illustrate the mechanism of gas adsorptivity. The fitting exhibits that the simulation data obtained are very close to Langmuir-Freundlich behavior, which emphasizes that the dominant adsorptivity has occurred in multi-layer adsorption. Moreover, the comparison between our simulation results and other reports, which studied these gases' adsorption on different nanoporous materials, experimentally and theoretically, is presented to illustrate that SiCNTs still have the best gas adsorptivity ability at ambient temperature and low/high pressure.

This study reports the first investigation of using a ceramic-carbonate dual-phase membrane to electrochemically separate CO 2 from a simulated natural gas. The CO 2 permeation flux density was systematically studied as a function of temperature, CO 2 partial pressure and time. As expected, the flux density was observed to increase with temperature and CO 2 partial pressure. Long-term stability test showed that flux density experienced an initial performance-improving "break-in" period followed by a slow decay. Post-test microstructural analysis suggested that a gradual loss of carbonate during the test could be the cause of the flux-time behavior observed. © The Author(s) 2015. Published by ECS.

Published January 24, 2015.Natural gas is a cleaner burning and flexible alternative to other fossil fuels, and is widely used in power generation, residential, industrial, and transportation sectors.1,2 Sources of natural gas include conventional onshore and offshore wells and unconventional wells that rely on stimulation technologies to enhance natural gas recovery in the reservoir. Examples of the latter include hydraulic fracturing in shale and water removing in coal bed methane (CBM) wells. 3,4The composition of natural gas varies considerably with sources, and even within a source. 5,6 Other than minor amounts of H 2 S, H 2 O, N 2 , He and VOC (volatile organic compounds), CO 2 concentration in a natural gas can vary from 0 to 70%, see Table I. As an acidic gas, CO 2 must be removed prior to transportation in order to protect pipelines. During the removal process, avoiding accidental CH 4 release to the atmosphere is also important since CH 4 is a heat-trapping gas 86 times more powerful than CO 2 . Therefore, a safe, efficient and low-cost separation process for CO 2 removal from raw natural gas is technologically and environmentally important.

Efficient CO₂ Removal for Ultra‐Pure CO Production by Two Hybrid Ultramicroporous Materials

et al. 2018

View full text Add to dashboard Cite

Removal of CO2 from CO gas mixtures is a necessary but challenging step during production of ultra-pure CO as processed from either steam reforming of hydrocarbons or CO2 reduction. In this contribution, two hybrid ultramicroporous materials (HUMs), SIFSIX-3-Ni and TIFSIX-2-Cu-i, which are known to exhibit strong affinity for CO2, were examined with respect to their performance for this separation. The single-gas CO sorption isotherms of these HUMs were measured for the first time and are indicative of weak affinity for CO and benchmark CO2/CO selectivity (>4000 for SIFSIX-3-Ni). This prompted us to conduct dynamic breakthrough experiments and compare performance with other porous materials. Ultra-pure CO (99.99%) was thereby obtained from CO gas mixtures containing both trace (1%) and bulk (50%) levels of CO2 in a onestep physisorption-based separation process. Carbon monoxide, CO, is a valuable reaction intermediate that is utilised for the synthesis of industrially important chemicals such as oxo-alcohols, phosgene, acetic acid and various liquid hydrocarbons.
