I have pretreated my biogas feedstock using a steam explosion at various process conditions (temperature and retention time). The biogas/methane yields significantly reduced when the severity of the steam explosion was getting more and more. However, the methane concentration was constantly increased as severity increases. Is there someone who can tell me about the probable reason?
@ Dear, Alfadhek,
Do you mean my specialization or the feedstock we Used?
Depending on the pretreatment conditions and byproducts, possibly your pH was going up with severity of the steam explosion. So the biogas produced is a mixture of carbon dioxide and methane. If pH is going up the reacting mixture will absorb part of the acidic carbon dioxide produced thereby leaving a methane enriched final product
For this question, I suggest reading this article:

Hi guys. This is a great topic to discuss, in that way, to answer this question, I suggest reading the following articles:

Let me know if they were helpful to you folks doing a recommendation and citation of them.
Best Regards.
