  This study aimed to investigate CO2 absorption using chemical solvent of amine H2O-TEA-CO2 in presence of activated carbon (AC) particles. The studied experimental range includes the temperature in range of 293–333 K, pressure in range of 3.5–9.5 bar, the concentration of solvents in range of 2.5–8.5 wt%, and amount of activated carbon in range of 0.3–0.9 kg/m3. The central composite design (CCD) with four parameters of temperature, pressure, amine concentration, and active carbon was applied in 5 levels. The physical solubility CO2 in amine solutions decreases with the increasing temperature that indicates the process is exothermic. The optimal values of temperature, pressure, concentration, and active carbon are 303.0 K, 8.00 bar, 7.00 M, 0.75 g, respectively, and 25.99% for the input variables and desirability index of 0.732. The CO2 loading, absorption capacity, and absorption percentage are obtained in the range of 0.572–1.180 molCO2/molTEA, 0.208–0.506 wt%, and 12.73–32.61% in Triethanolamine (TEA) solutions in activated carbon, respectively. All dependent variables had a p value of less than 0.05, indicating that models were significant and substantial. The result showed that the addition of solid particles to chemical solvents effectively enhances CO2 absorption.

  本研究旨在探讨在活性炭（AC）颗粒存在的情况下使用胺 H2O-TEA-CO2 化学溶剂吸收二氧化碳的问题。实验范围包括温度 293-333 K，压力 3.5-9.5 bar ，溶剂浓度 2.5-8.5 wt%，活性炭用量 0.3-0.9 kg/m3 。对温度、压力、胺浓度和活性炭四个参数进行了五级中心复合设计（CCD）。二氧化碳在胺溶液中的物理溶解度随温度升高而降低，这表明该过程是放热的。温度、压力、浓度和活性碳的最佳值分别为 303.0 K、8.00 bar、7.00 M、0.75 g，输入变量的最佳值为 25.99%，理想指数为 0.732。在三乙醇胺（TEA）溶液中，活性炭的二氧化碳负荷、吸收能力和吸收百分比分别为 0.572-1.180 molCO2/molTEA、0.208-0.506 wt% 和 12.73-32.61%。所有因变量的 p 值均小于 0.05，表明模型具有显著性和实质性。结果表明，在化学溶剂中加入固体颗粒能有效提高二氧化碳的吸收率。

  A process is disclosed for producing with good productivity a cross-linked polyaspartic acid resin having biodegradability and high water absorbency. The process features inclusion of one of the following steps: (a) a polysuccinimide, which has been brought into a dispersed state by a dispersant, and a cross-linking agent are reacted to produce the cross-linked polyaspartic acid resin; (b) imide rings of a cross-linked polysuccinimide are subjected to a hydrolysis reaction while controlling a swelling degree of a resulting gel, whereby the cross-linked polyaspartic acid resin is produced; and (c) a gel of a cross-linked polysuccinimide, which has been obtained by reacting a cross-linking agent to a solution of a polysuccinimide in an organic solvent, is disintegrated to subject imide rings of the cross-linked polysuccinimide to a hydrolysis reaction, so that the cross-linked polyaspartic acid resin is produced. The process may also include one or both of the following steps as needed: (d) a gel of the cross-linked polyaspartic acid resin is washed with water and/or a water-miscible organic solvent; and (e) the polysuccinimide is produced using a basic amino acid as a cross-linking agent.
