Regarding the components of biogas
Thread Content
Do the components of biogas produced by the fermentation of different raw materials (such as distillers’ grains, straw, kitchen waste, livestock manure, etc.) vary significantly? Mainly, what is the residual oxygen content approximately? Thank you all!
The protein content affects the CO2 level, which in turn influences the methane level; in addition, the levels of H2S and ammonia also have an impact. The residual oxygen content is generally very low, at the ppm level or undetectable.
