Abstract
Hydrogen has gained a lot of attention in the energy industry in the hopes of achieving clean sources of energy. Microwave-driven methane pyrolysis is a new method proposed to produce hydrogen. Microwave energy is implemented due to the efficiency and electrification of the process. However, natural gas would be the feedstock used on a commercial scale which explains the motivation behind this thesis. This thesis investigates a natural gas pyrolysis process by microwave heating for clean hydrogen production, utilizing a representative sample of pipeline natural gas. Natural gas was injected in a fluidized bed reactor filled with heated carbon particles inside a microwave cavity. The results showed that the natural gas breaks down to mainly hydrogen and solid carbon particles with a >90% methane conversion rate and hydrogen yield. In addition, natural gas pyrolysis can no longer be called emission free but rather low-carbon due to the presence of carbon dioxide in the natural gas.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
