Synthèse de nanofilaments de carbone à partir de polymères recyclés
NanoF-PoRes (Nano-Filaments from polymeric residues) is a synergetic project between PRIMA, KWI Polymers, Soleno and Université de Sherbrooke (UdeS) based on UdeS intellectual property (IP), and the nano-additive dispersion technology of KWI Polymers. The overall objective of the project is the development and scale-up of a carbon nanofilaments (CNF) synthesis process, which includes R&D work on two novel thermocatalytic reactors configurations (an auto-thermal pyrolyzer (ATP) and a fluid+mobile catalytic bed) and the evaluation of the so-derived product (CNF) as a polymers additive. The process is based on US patent 7,794,690 on Carbon sequestration and US patents applications 20,070,253,886, 20,050,220,695 owned by UdeS. The first step of the project is to adapt the patented process to use non-recyclable polymers (which are disposed in landfills) as raw materials to produce the synthetic gas+liquid. The catalyst for the hydrocarbon reforming is based on US patent application 20,120,273,728 and needs to be integrated in the proposed process. The catalyst for CNF growth is based on US patent application 20,090,203,519 and will be adapted to the process to control the shape and catalyst % contained in the CNF. A 1kg/h CNF synthesis kg-lab reactor and an ATP reactor processing the waste/residual polymers will be developed during the project and the synthesized CNF will be compounded by the KFusionTM process developed by KWI specially to integrate additives. The overall plus-value generated by this project is that waste/residual polymers will be valorised as CNF, which, as additives, raise the quality of recycled polymers so that KWI recycled composite polymers will meet the specifications expected by its partner Soleno.
