The characteristics and CO2 adsorption ability of honeycomb carriers including zeolite and cordierite, following modification by Tetraethylenepentamine (TEPA), were examined in this study. Experiment setups included batch, progressive and breakthrough curves isotherm adsorption. In this study, analyses of microstructures for honeycomb material were done with scanning electron microscopy (SEM), X-ray diffraction analyzer (XRD), nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR) and specific surface area analyzer. The actual modified amount quantity of grafted between zeolite and cordierite differed by 2.2 times. Batch experimental results showed that amines honeycomb zeolite can reduce the CO2 concentration to less than the law (first law: 600 ppm; second law: 1000 ppm), but cordierite takes two hours. The results show that the adsorption capacity (x/m) were HZT30>HZT40>HZT20>HCH4T60. The Langmuir isotherms are by linear regression, R2 values greater than 0.98, and favorable adsorption assessment by the parameter values. It shows that amines honeycomb zeolite is effective for adsorption of CO2. Moreover, honeycomb zeolite dynamical data is fit for the pseudo-second-order kinetic model (R2 > 0.99). Amine honeycomb zeolites have a good physical and chemical properties as well as high adsorption capacity. In this study, the best adsorption performance honeycomb zeolite is modified by the the amine dose of 25 wt%. Chu-Chin Hsieh 謝祝欽 2013 學位論文 ; thesis 105 zh-TW |
