| 摘 要： | 为了脱除CO2温室气体,提出了利用氨水土壤混合物去除CO2的新方法。分别考察了土壤颗粒粒径、CO2初始流量、氨水浓度（质量比）和温度对CO2脱除量和脱除率的影响。实验结果表明,该方法去除CO2的量较土壤物理吸附量和氨水化学吸收量的总和提高了大约15%;随着氨水浓度的增大,CO2的脱除率和脱除量都增大;随着土壤颗粒粒径和CO2初始流量的增大,CO2的脱除率和脱除量都减小;当温度由22℃升高到31℃,CO2的脱除率随着温度的升高而增大,但是继续升高温度到40℃,CO2的脱除率反而下降。

| Abstract: | A new method was proposed for removing CO2 greenhouse gas by using the mixture of ammonia and soil.The effect of soil particle size,CO2 initial flux,ammonia concentration and temperature on CO2 removal capacity and CO2removal efficiencies were investigated respectively.The experimental results show that CO2removal capacity of this method is 15% larger than the sum of soil physical adsorption capacity and ammonia absorption capacity;CO2 removal efficiencies and removal capacity increase with increase of ammonia concentration and decrease with increase of CO2 initial flux and soil particle size ; when the temperatures increase from 22 ℃ to 31 ℃ , the CO2 removal efficiencies increase with the increasing temperatures, and then fall when the temperatures continue to rise to 40 ℃. |
