Valorization of pyrolysis of non-condensable gases to valuable monomers and dechlorination study

The valorization of non-condensable gases formed during pyrolysis of polyethylene and polypropylene wastes is the main target of this project. The gaseous olefins will be converted via cross-metathesis in the presence of heterogeneous catalysts and or homogeneous moieties immobilized on oxidic supports. Catalysts formulations showing high activity and selectivity in converting ethylene and or butenes to propylene will be further refined in terms of composition and operating variables to maximize the yield to the desired olefin. The effect of impurities in the non-condensable stream will be also explored. Reaction conditions optimization and kinetic modelling as well as reactor configuration will be part of the work.
