由于温室效应导致的全球变暖正在加剧，人们正在努力减少二氧化碳的排放，二氧化碳是碳质材料燃烧产生的一种主要温室气体。在高通量微孔管中微通道反应器(MTMCR)中，研究了N-甲基二乙醇胺(MDEA)溶液和有效活化剂哌嗪(PZ)对含N_2混合气体中CO_2的化学吸收。MTMCR作为一种新型的微反应器，由于其较大的气液界面面积，极大地强化了气液传质。考察了不同工艺参数对总体积传质系数和CO2脱除效率的影响。结果表明，传质系数和脱碳率均随液体流量、温度和液体溶剂浓度的增加而增大。气液传质效率随着MTMCR微孔尺寸和环形通道尺寸的减小而增大。当气体和液体的流量分别为100g L/h和5.32g−/h时，当醇胺溶液中含有10wt%的MDEA和4wt%的PZ时，体积传质系数和CO2脱除效率分别达到1.70%和97%。
Global warming due to greenhouse effects is on the rise, and many efforts to reduce emissions of CO2which is a major greenhouse gas from combustion of carbonaceous materials are being made. In this study, chemical absorption of CO2into N-methyldiethanolamine (MDEA) solution combined with effective activator piperazine (PZ), from a gas mixture containing N2was carried out in a high-throughput microporous tube-in-tube microchannel reactor (MTMCR). As a novel microreactor, MTMCR greatly intensifies gas–liquid mass transfer due to its large gas–liquid interfacial area. The effects of different parameters on the overall volume mass transfer coefficient and CO2removal efficiency were investigated. The results showed that both mass transfer coefficient and CO2removal efficiency increased with an increase in the liquid flow rate, temperature and concentration of liquid solvent. Also, the gas–liquid mass transfer efficiency increased with a decrease in the size of the micropore and annular channel of MTMCR. The volume mass transfer coefficient and CO2removal efficiency reached 1.70 s−1and 97%, respectively, at flow rates of 100 L/h and 5.32 L/h for gas and liquid respectively, with alkanolamine solutions containing 10 wt.% MDEA and 4 wt.% PZ.
