Assessment of co-pyrolysis of polyethylene terephthalate with waste cooking oil: Kinetic study and impact on the chemical constituents of the liquid product.

Post-consumer waste management systems have proven insufficient to meet the growing global demand. In this context, adopting alternative pathways that complement established practices, such as chemical recycling, becomes essential. Accordingly, this study evaluated the potential of the co-pyrolysis process to manage polyethylene terephthalate (PET) residues and waste cooking oil (WCO), converting them into industrial inputs.

Renewable Hydrocarbon Production from Waste Cottonseed Oil Pyrolysis and Catalytic Upgrading of Vapors with Mo-Co and Mo-Ni Catalysts Supported on γ-AlO.

In this work, the production of renewable hydrocarbons was explored by the means of waste cottonseed oil (WCSO) micropyrolysis at 500 °C. Catalytic upgrading of the pyrolysis vapors was studied using α-AlO, γ-AlO Mo-Co/γ-AlO, and Mo-Ni/γ-AlO catalysts. The oxygen removal efficiency was much lower in non-catalytic pyrolysis (18.
