摘要

In the current study, multiwall carbon nanotubes (MWCNTs) were functionalized with Tetraethylene Pentamine (TEPA) and added into polyurethane (PU) polymer matrix to prepare PU-MWCNT-TEPA nanocomposite membranes. The prepared membranes were characterized using FT-IR, XRD and SEM analysis. The analysis results showed that MWCNTs were properly functionalized with TEPA and also uniformly dispersed in polymer matrix. The CO2 permeability increased by 99.8% at 10 wt.% loading of MWCNTs-TEPA. The nanocomposite membrane's CO2/CH4 selectivity was also increased by 9.6%. Impacts of operating pressure and temperature on the membranes' CO2 permeability and CO2/CH4 ideal selectivity were also investigated. Finally, the gaseous penetrants permeabilities through the nanocomposite membranes were predicted using the Maxwell, the KJN, and the modified KJN models by AAREs of 31.4-35.2, 27.8-31.6, and 4.4-5.7%, respectively.

Preparation and characterization of modified halloysite nanotubes-Pebax nanocomposite membranes for CO2/CH4 separation

Rezvan Habibi, Omid Bakhtiari

Summary: In this study, halloysite nanotubes (HNTs) filler particles were treated in a basic solution to improve dispersion in Pebax matrix, resulting in enhanced gas separation performance of the modified HNTs-Pebax nanocomposite membranes. The CO2 adsorption capacity and gas permeation properties of the membranes were significantly improved compared to neat Pebax membranes, approaching the Robeson upper bound limit for gas separation membranes.

Wenhao Zou, Hongtao Shang, Xiaolong Han, Peng Zhang, Xingzhong Cao, Ping Lu, Chao Hua

Summary: New robust membrane materials for separating carbon dioxide are gaining more attention. In this study, three polyphosphazene materials were synthesized and corresponding composite membranes were prepared. Gas permeation tests showed that POA/PVDF membrane had the highest CO2 permeability due to the largest free volume.

Isopropanol accelerated crystallization of AlPO-18 membranes for CO2/CH4 and N2/CH4 separations

Ting Wu, Ying Tu, Wen Liu, Zhen Sun, Meihua Zhu, Xuezhong He, Tian Gui, Xiangshu Chen, Hidetoshi Kita

Summary: In this study, a co-solvent strategy using isopropanol as the organic co-solvent was employed to synthesize AlPO-18 membrane. The addition of isopropanol not only accelerated the crystallization of AlPO-18 membrane, but also increased the size of crystals on the membrane, leading to a reduced synthesis time.

CO2/CH4 mixed-gas separation in PIM-1 at high pressures: Bridging atomistic simulations with process modeling

Marcel Balcik, S. Birgul Tantekin-Ersolmaz, Ingo Pinnau, M. Goktug Ahunbay

Summary: Polymeric membranes with intrinsic microporosity, such as PIM-1, have been extensively studied for gas separation applications. The simulation results showed competitive adsorption behavior favoring CO2 but increased CH4 permeabilities in mixed-gas conditions, impacting the selectivity of the polymer. The study also developed a macroscopic permeability model to relate multicomponent permeability to feed gas conditions, providing potential for future process simulation tools.

Non-linear high Tg polyimide-based membranes for separating CO2/CH4 gas mixtures

Zeljka P. Madzarevic, Beatriz Seoane, Jorge Gascon, Maruti Hegde, Theo J. Dingemans

Summary: A series of membranes based on non-linear all-aromatic polyimides were investigated to understand how their backbone geometry and local electrostatics influence gas transport and CO2/CH4 separation ability. The results showed that the non-linear backbone geometry promotes CO2 permeability, while the presence of an electrostatic dipole moment associated with the 1,3,4-oxadiazole heterocycle governs CO2/CH4 separation selectivity.

Polyurethane-based membranes for CO2 separation: A comprehensive review

Farhad Ahmadijokani, Hossein Molavi, Salman Ahmadipouya, Mashallah Rezakazemi, Ahmadreza Ghaffarkhah, Milad Kamkar, Akbar Shojaei, Mohammad Arjmand

Summary: The membrane process is a promising technology for CO2 capture due to its environmental-friendly features and low cost. However, the gas selectivity of polyurethane-based membranes is relatively low, which limits their practical application. This review focuses on the key factors affecting the gas transport properties and gas separation performance of these membranes, and summarizes the recent progress in polyurethane-based membranes.

Multi-scale design of MOF-based membrane separation for CO2/CH4 mixture via integration of molecular simulation, machine learning and process modeling and simulation

Xi Cheng, Yangyanbing Liao, Zhao Lei, Jie Li, Xiaolei Fan, Xin Xiao

Summary: In this work, a multi-scale design framework of MOF-based membrane separation for CO2/CH4 mixture is proposed, which integrates molecular simulation, machine learning, and process modeling and simulation. The adsorption isotherms, permeability, and selectivity of a MOF-based membrane (IRMOF-1) for CO2/CH4 separation are evaluated using molecular simulation. Prediction models of adsorption capacity and self-diffusivity are established using machine learning methods, and then integrated with membrane separation process modeling. Case studies demonstrate the feasibility and superiority of the proposed integrated framework.

PEI@MOFs thin film nanocomposite (TFN) membrane for efficient CO2 separation

Yingnan Ma, Na Liu, Shaohua Tang, Xingyan He, Jiachen Chu, Lelin Zeng, Panliang Zhang, Kewen Tang

Summary: A novel thin film nanocomposite (TFN) membrane consisting of polyetherimide (PEI) and metal-organic framework (MOFs) was developed for efficient CO2 separation. The MOFs in the TFN membrane increased the diffusion coefficient and selectivity for CO2, while the ultra-thin functional layer minimized the CO2 transport resistance. The PEI@MOFs TFN membranes exhibited high CO2 permeance and enhanced CO2 separation performance close to the Robeson upper bound, and also showed good thermal and operation stability.

Andrea Coletto, Pietro Poesio

Summary: Experiments and simulations were conducted to study the air volume fraction and hold-up in a bubble channel reactor. A new signal processing method was proposed to avoid the loss of bubble residence time. The results were in agreement with previous studies and a bubble-scale model was developed to explain the relationship between hold-up and air superficial velocity.
