摘　　要：全球气候变暖已经成为一项世界性的环境问题,温室气体的主要成分CO_(2)的减排成为人们关注的焦点。现今各国都在研究降低CO_(2)排放的措施,希望能够开发一种易于工业化应用的吸收剂。通过研究黄腐酸浓度、CO_(2)流量、反应温度、吸收时间和循环次数对黄腐酸吸收CO_(2)效果的影响,探索黄腐酸作为CO_(2)吸收剂的新工艺。结果表明,黄腐酸吸收CO_(2)的最佳反应条件:黄腐酸浓度为0.03 g/mL、反应大气压为1.01×10^(5)Pa、吸收时间为60 min、反应温度为20℃,CO_(2)流量为0.14 L/min。黄腐酸吸收CO_(2)的循环次数可超过20次之多,CO_(2)吸收量随着黄腐酸循环次数的增加整体呈下降趋势。As global warming has become a worldwide environmental problem,CO_(2),the main part of GHG,is focused on reducing its emissions.At present,all countries are studying measures to reduce CO_(2)emissions,hoping to develop an absorbent that is easy to be used in industrial applications.The effects of fulvic acid concentration,CO_(2)flow rate,reaction temperature,absorption time and circulation times on CO_(2)absorption were studied to find a new process of fulvic acid as CO_(2)sorbent.The results showed that the optimum reaction conditions for the absorption of CO_(2)by fulvic acid concentration were 0.03 g/mL,1.01×10^(5)Pa,60 min absorption time,20℃reaction temperature,and 0.14 L/min CO_(2)flow rate.The numbers of cycles of CO_(2)uptake by fulvic acid were more than 20 times,while the trend of CO_(2)absorptive amount was decreasing with the increase of fulvic acid cycle times.
