2023年9月15日 · CH 4 and CO 2 hydrate phase equilibrium in the presence of polyethylenimine (PEI) were presented. Induction time was measured to identify the kinetic effect of PEI on the …

2019年2月13日 · Novel PEI-impregnated UiO-66 (PEI@UiO-66) composites with enhanced CO2 adsorption capacity and CO2/CH4 selectivity were synthesized and characterized. The …

混合基质膜研究了纯气体 （CO2） 和混合气体 （CO2/CH4） 的渗透性和选择性。 在 PSF 基质中混合的 5 wt% ZIF-8@PEI 时最高。 在纯气体研究中，我们研究了与 ZIF-8/PSF MMM …

采用浸渍法将聚乙烯亚胺 (PEI)负载到MIL-101 (Cr)上.采用X线衍射仪 (XRD),傅里叶变换红外光谱仪 (FT-IR),热分析仪 (TG)和N2吸附脱附对改性MIL-101 (Cr)吸附剂进行表征.测试改性MIL-101 …

CH4 has no effect on the structure of H2O clusters, while H2O makes CH4 together more tightly. Finally, the self-diffusion coefficients of H2O, CH4, and CH4/H2O mixture are calculated....

2024年12月1日 · In the case of CH 4, the maximum CH 4 molecules are retained over the surface ZIF-8@PEI. The CH 4 permeability is not increased; it is to be constant (0.71, 0.73, 075 …

2015年10月8日 · Novel PEI-impregnated UiO-66 (PEI@UiO-66) composites with enhanced CO 2 adsorption capacity and CO 2 /CH 4 selectivity were synthesized and characterized. The …

Here, we present high selectivity MMMs based on structural regulation of UiO-66-PEI fillers grafted with polyzwitterion. XRD, FTIR, SEM and TGA characterization techniques were used …

2023年12月15日 · The PEI@CuBDC TFN membrane exhibited CO 2 permeance of 15.6 GPU (3.3 times higher than the neat PEI membrane), and the selectivity of CO 2 /CH 4 reached …

The results showed that the interaction strength of amine-functionalized MIL-101 (Cr) with carbon dioxide was greatly increased, which improved the adsorption capability of CO2 and …
