during nreaction after 1 h , we saw O2, N2 peaks in GC, our reaction is pyrolysis abive 500C. It is hard to figure out where these compounds are coming either from the reactor or the catalyst?
How did you verify that you have no leak? What is the N2/O2 ratio? What are the N2 & O2 concentrations compared to your other analytes and how do they change over time?
