“…To facilitate the formation of •OH to accelerate the Fenton reaction, various systems, such as photo-Fenton, electro-Fenton, bio-Fenton, and Sono-Fenton systems, have been studied for the decomposition of organic matter. For example, Chow et al 80 further shined UV light to the reaction system, effectively accelerating the degradation of PE, PP, and PVC to CO 2 (Figure 7A). Ghatge et al 81 explored F I G U R E 8 (A) Catalytic performance and product distribution on microwave-assisted recycling.…”

The mass production of disposable polyolefin products has led to serious plastic pollution and an imbalance between manufacturing and recycling. Given these challenges, the chemical upcycling of waste polyolefins has attracted extensive attention due to its high efficiency and economic benefits. Herein, we review the development of polyolefin chemical upcycling in heterogeneous catalysis. The status quo of polyolefin recycling is first discussed. We then introduce the advanced strategies for chemical upcycling in the view of different value‐added products and discuss their challenges and prospects. Our in‐depth analysis centers on the catalytic mechanism and the design principle of heterogeneous catalysts. Finally, we outlook the promising directions to facilitate the degradation process via polymer and catalyst design and optimized catalytic engineering. Innovative strategies are expected to promote the chemical upcycling of polyolefins, bringing great promise for the sustainable development of society.

“…Chemical treatment of PVC with Fenton catalyst reported by Chow et al [74] activates the surface of PVC by coordinating sulphonated groups which are tagged by FeCl 3 . Breakdown of an entire polymer using an oxidant hydrogen peroxide degrades numerous organic acids and CO 2 in 10 min with a degradation efficiency of 98%.…”

No presente trabalho foram realizadas simulações visando comparar os resultados obtidos, em termos de composições dos produtos, com aqueles encontrados na literatura para esse tipo de reação, e ainda avaliar a influência desses resultados na capacidade energética dos produtos. As simulações foram realizadas com o auxílio do software de simulação Aspen Plus®, simulando a operação em um Reator de Gibbs. As condições de pressão e temperatura simuladas, que corresponderam àquelas usadas na literatura para viabilizar a comparação de resultados, foram alteradas de modo a se identificar a influência das mesmas no processo. Os dados gerados nas simulações foram analisados e a partir deles foi possível determinar como condições ideais de pressão e temperatura 382 ºC e 0,14 MPa; além da composição ideal de cada polímero a ser alimentada no reator (51% PE, 41% PP e 8% PS); a autossuficiência do processo, em termos energéticos, utilizando a corrente gasosa dos produtos da pirólise para gerar energia capaz de fundir a corrente de alimentação do reator e suprir a necessidade energética do mesmo e a capacidade do sistema de produzir trabalho útil, via aplicação de um ciclo Otto, no valor de 3,615 kW/kg.
