摘要：In this work, a novel nanofluid containing amino-modified carbon nanoparticles with enhanced stability and performance was prepared for CO2 absorption. SEM, TEM, EDS, FT-IR, Raman and XPS were employed to characterize the micro-structure, element, functional groups of the amine functionalized carbon nanosphere particles (APTES-CNSs). Moreover, APTES-CNSs nanofluids stability was comprehensively evaluated by Ultraviolet-visible spectrophotometer (UV-Vis). The CO2 absorption performance experiments, including the effect of solid content, temperature, amine solution concentration and flow rate, were carried out in a batch. The results indicated that a high stability of APTES-CNSs in the N-methyldiethanolamine (MDEA) solution. Besides, under the condition of 0.8 g/L solid content and the temperature of 30 degrees C, the enhancement index of CO2 absorption was more significant and reached 1.25 compared with the amine solution. The advantageous performance ensured the potential of APTES-CNSs nanofluids as advanced absorbents.
