▎ 摘  要

NOVELTY - Pyrolysis process activated by nanocarbon-based metal free reagents to obtain synthetic fuels from plastic waste, involves (i) adding a feedstock of plastic waste and a nanocarbon-based metal free reagent to a pyrolysis reactor at room temperature and atmospheric pressure, (ii) increasing the reactor temperature up to 500° C, and a pressure 1-20 bar during a period of time 1-3 hours for a thermal decomposition, (iii) separating the gases generated in the reactor in different fractionating columns, obtaining thus different fractions, (iv) cooling the gas fractions obtained in the step (iii) in a condenser obtaining a liquid fraction, and (v) extracting the resulting liquid fraction as the final product, where the nanoparticle carbon-based metal free reagent is chosen from graphene, carbon nanotubes, and/or carbon nanowires. USE - The process is used for pyrolysis activated by nanocarbon-based metal free reagents to obtain synthetic fuels from plastic waste. ADVANTAGE - The process allows use of lower temperatures and pressures, reduces process cost, avoids use of strategic gases such as helium or argon, is environmentally friendly and more economic, and achieves yield greater than 80% of the liquid fraction.
