如何區分甲烷和一氧化碳

最初, it’s important to recognize that both pure methane and carbon monoxide are devoid of odor, 而沼氣由於額外嘅氣體而散發出難聞的氣味, 要smell成為無效嘅識別工具.

適當的方法是點燃這些氣體並觀察它們的燃燒行為. Methane combustion generates a greater number of water molecules compared to that of carbon monoxide.

By individually igniting each gas and then covering the 火焰 with a dry, cool beaker, the formation of condensation on the beaker’s interior signifies methane, whereas its absence indicates carbon monoxide.
