“…Primary products of pyrolysis are liquid, gas, and coke. The extent of decomposition (yield) and the quality of pyrolysis products depend on the composition of the source material,5–7 the temperature‐time history,8, 9 pressure,10–12 residence time (secondary reaction),13, 14 and presence of other reactants such as water,15–18 methane,19 O 2 ,20 CO 2 ,21 etc. Because of the chemical composition of the oil produced, moderate to significant upgrading (nitrogen removal and/or hydrogen addition) may be required to convert the oil into a refinery feedstock 22–24.…”
