Catalytic pyrolysis of leucine and proline were carried out in a micro-furnace pyrolyzer.
Distributions of carbon, oxygen and nitrogen were comparatively investigated.
Leucine yielded 29.6% aromatic hydrocarbons, 34.9% olefins, and 8.1% alkanes.
Proline yielded 25.3% aromatic hydrocarbons, 14.0% olefins, and 5.5% alkanes.
Insights into the deoxygenation pathways of leucine and proline were elucidated.
