摘要: 发酵生物气通常包含多种可再生优质能源气体,具有成分复杂、组成多变的性质。本研究建立发酵生物气主要成分的气相色谱分析法,可同时分离氢气、氮气、甲烷和二氧化碳4种气体。在定量分析中,得到了线性范围内拟合度较高的标准曲线,并且该方法的精密度和准确度较高。将该方法用于餐厨垃圾两相厌氧发酵产氢产甲烷批式试验的发酵气成分分析,获得了气相主要成分的变化规律。

Abstract: Fermentation biogenic gas is generally composed of several renewable energy gases with complex and changeable composition. A method for determination of hydrogen, nitrogen, methane and carbon dioxide simultaneously in fermentation biogenic gas was established by gas chromatography in this study. The chromatographic peaks were identified efficiently. The standard curves were well fitted in their linear ranges and the component analysis method was capable of very high precision and accuracy. This method was applied in the component analysis of the produced gas in two-stage hydrogen-methane fermentation process for treating food waste, and the way of main composition of fermentation gas change in batch experiment was achieved.

Key words: fermentation biogenic gas, gas chromatography, component analysis, thermal conductivity detector
