| 1 | Numerical simulation of low-concentration CO_(2) adsorption on fixed bed using finite element analysis显示文摘Accurately predicting distributions of concentration and temperature field in fixed-bed column is essential for designing adsorption processes.In this study,a two-dimensional(2D),axisymmetric,nonisothermal,dynamic adsorption model was established by coupling equations of mass,momentum and energy balance,and solved by finite element analysis.The simulation breakthrough curves fit well with the low-concentration CO_(2) adsorption experimental data,indicating the reliability of the established model.The distributions of concentration and temperature field in the column for CO_(2) adsorption and separation from CO_(2)/N_(2) were obtained.The sensitivity analysis of the adsorption conditions shows that the operation parameters such as feed flow rate,feed concentration,pellet size,and column height-to-diameter ratio produce a significant effect on the dynamic adsorption performance.The multi-physics coupled 2D axisymmetric model could provide a theoretical foundation and guidance for designing CO_(2) fixed-bed adsorption and separation processes,which could be extended to other mixed gases as well. | Yonghou Xiao Shuang Qiu Qidong Zhao Yuhao Zhu Chirag BGodiya Gaohong He | 2021 | Chinese Journal of Chemical Engineering2021，34，8： | 2 |
| 2 | New high permeable polysulfone/ionic liquid membrane for gas separation显示文摘In this study,the effects of 1-Ethyl-3-methylimidazolium tetrafluoroborate ionic liquid on CO2/CH4 separation performance of symmetric polysulfone membranes are investigated.Pure polysulfone membrane and ionic liquid-containing membranes are characterized.Field emission scanning electron microscopy(FE-SEM)is used to analyze surface morphology and thickness of the fabricated membranes.Energy dispersive spectroscopy(EDS)and elemental mapping,Fourier transform infrared(FTIR),thermal gravimetric(TGA),X-ray diffraction(XRD)and Tensile strength analyses are also conducted to characterize the prepared membrane s.CO2/CH4 separation performance of the membranes are measured twice at 0.3 MPa and room temperature(250 C).Permeability measurements confirm that increasing ionic liquid content in polymer-ionic liquid membranes leads to a growth in CO2 permeation and CO2/CH4 selectivity due to high affinity of the ionic liquid to carbon dioxide.CO2 permeation significantly increases from 4,3 Barrer(1 Barrer=10^-10 cm^3(STP)·cm·m^-2·s^-1·cmHg^-1,1 cmHg=1.333 kPa)for the pure polymer membrane to 601.9 Barrer for the 30 wt%ionic liquid membrane.Also,selectivity of this membrane is improved from 8.2 to 25.8.mixed gas te sts are implemented to investigate gases interaction.The results showed,the disruptive effect of CH4 molecules for CO2 permeation lead to selectivity decrement compare to pure gas te st.The fabricated membranes with high ionic liquid content in this study are promising materials for industrial CO2/CH4 separation membranes. | Mohadeseh Farrokhara Fatereh Dorosti | 2020 | Chinese Journal of Chemical Engineering2020，28，9： | 1 |
