Pyrolysis of plastic waste is a very interesting process because the hydrocarbons produced by this reaction can be used as energy carriers. Non-catalytic, this process leads to the production of a relatively poor quality liquid oil and requires a relatively high operating temperature. The use of a catalyst in the pyrolysis reactor makes it possible to convert 70-80 % of plastic waste into a much higher quality liquid oil, which can therefore be used in several energy-related applications, such as electricity generation, transport fuels and heating. Despite the benefits of catalytic pyrolysis, some limitations persist, such as process energy consumption, cost and re-use of the catalyst. In order to meet these challenges, this project proposes to study (i) the ability of optimised catalysts to remain active and selective during several pyrolysis cycles (ii) catalyst regeneration and (iii) the impact of regenerated catalysts on the yield and composition of oils derived from catalytic pyrolysis of polyethylene. The thesis will be co-financed by Neo-eco, an industrial partner of the joint laboratory-company team PYROCAT. (English) | |||||||||||||||

La pyrolyse de déchets plastiques est un procédé très intéressant car les hydrocarbures produits par cette réaction peuvent être utilisés comme vecteurs énergétiques. Non catalytique, ce procédé conduit à la production d’une huile liquide de qualité relativement médiocre et requiert une température de fonctionnement relativement élevée. L'utilisation d'un catalyseur dans le réacteur de pyrolyse permet la conversion de 70 à 80% des déchets plastiques en une huile liquide de bien meilleure qualité et qui en conséquence peut être utilisée dans plusieurs applications liées à l'énergie, telles que la production d'électricité, les carburants pour le transport et le chauffage. Malgré les avantages de la pyrolyse catalytique, certaines limitations persistent telles que la consommation énergétique du procédé, le coût et la réutilisation du catalyseur. Afin de relever ces défis, ce projet propose d’étudier (i) l’aptitude de catalyseurs optimisés, à rester actifs et sélectifs pendant plusieurs cycles de pyrolyse (ii) la régénération des catalyseurs et (iii) l’impact des catalyseurs régénérés sur le rendement et la composition des huiles dérivées de la pyrolyse catalytique du polyéthylène. La thèse sera cofinancée par Neo-eco, partenaire industriel de l’équipe mixte laboratoire-entreprise PYROCAT. (French)
