利用气相色谱仪检测ＣＯ２浓度，测量了不同条件下ＮａＯＨ溶液对ＣＯ２的瞬时捕集效率Ｅ，实验气体以流量１Ｌ／ｍｉｎ通过２００ｍＬ浓度为５ｍｏｌ／Ｌ的ＮａＯＨ溶液，使用多孔滤板、三孔和单鼓泡器时，Ｅ分别为９５％、７８％和７７％。用多孔滤板鼓泡器，气体流量为０．５、１．０、１．２和１．５Ｌ／ｍｉｎ时，Ｅ分别为９８％、９５％、９０％和８６％。当ＮａＯＨ溶液浓度从０．５～５ｍｏｌ／Ｌ以及体积从１００～２００ｍＬ变化时，Ｅ基本不变。但取样温度低于１５℃时，Ｅ有明显变化。本文还分析了瞬时捕集效率与累积捕集效率的关系。对ＣＯ、ＣＨ４、Ｃ２Ｈ６、Ｃ３Ｈ８和Ｃ４Ｈ１０的催化氧化效率也进行了研究。 CO2 gas chromatography was used to measure the CO2 capture efficiency under different conditions. The experimental gas E was fed at a flow rate of 1 L / min through a 200 mL NaOH solution with a concentration of 5 mol / L, using a porous filter plate, three holes and Single bubbler, E were 95%, 78% and 77%. E was 98%, 95%, 90% and 86%, respectively, with porous filter plate bubblers at gas flow rates of 0.5, 1.0, 1.2 and 1.5 L / min. When NaOH solution concentration from 0.5 ~ 5mol / L and volume from 100 ~ 200mL change, E basically unchanged. However, when the sampling temperature is below 15 ° C, E changes significantly. The paper also analyzes the relationship between instantaneous capture efficiency and cumulative capture efficiency. The catalytic oxidation efficiencies of CO, CH4, C2H6, C3H8 and C4H10 were also investigated.
