Hello,

The H/C_eff ratio gives us valuable clues about the kind of products you might expect from the pyrolysis process being it bio-oil, syngas, or char. It's all about understanding how hydrogen and carbon play together in your feedstock, which is crucial for tailoring the pyrolysis process to get the results you're after.

Now, I'm curious about a few things regarding your experiment that could help me provide you with more tailored advice. For starters, how did you go about preparing your samples for the elemental analysis? Also, the presence of certain elements like oxygen, nitrogen, and sulfur can really change the game due to how they interact with hydrogen. Have you noticed any specific compounds or peculiarities in your feedstocks that caught your eye? Sharing these details could really help in dissecting the H/C_eff ratio calculation and ensuring you're on the right track for your pyrolysis project.

Let me know and maybe can help you to solve ratio. I've been in that problem and it comes to the process.
