离子交换树脂固态胺复合材料的制备、表征及CO2吸附
Preparation, characterization and CO2 adsorption of ion exchange resin supported solid amine adsorbents
摘要
Abstract
A series of solid amine adsorbents were prepared by using three different preparation methods with ion exchange resin (D001) as carrier and with tetraethylenepentamine (TEPA) as modifier. The sorbents were characterized by nitrogen adsorption/desorption, Fourier transform infrared spectroscopy ( FT-IR ) and thermogravimetric analysis ( TGA) techniques. The effects of TEPA loadings, adsorption temperatures, influent gas flow rates and CO2 partial pressure on the CO2 adsorption capacity in a fixed bed reactor were investigated. The results show that the solid amine adsorbent prepared by the coordination method has a better dispersibility and stability, and the maximum CO2 adsorption capacity is 4 mmol/g when the TEPA loading is 40%, the adsorption temperature is 65℃ and the influent gas flow rate is 40 mL/min. The amount of CO2 adsorption only decreases by 3. 98% and remains almost unchanged after 10 cycles of desorption and desorption. The study of thermodynamics and kinetics indicates that the adsorption mechanism is dominated by both chemical and physical adsorption.关键词
