플라스틱은 가공과 처리가 간단하여 매년 생산량이 증가하고 있으며 이에 따라 플라스틱 폐기물의 양 또한 매년 증

가하고 있다. 플라스틱 폐기물 문제를 해결하기 위하여 촉매를 활용한 업사이클링 공정은 유망한 해결책으로 제시되

고 있다. 다양한 금속(Ru, Pt 등) 및 지지체(TiO2, CeO2 등)가 폴리 올레핀계 플라스틱의 화학적 재활용에 적용되었다.

입자 크기를 조절하고, 지지체의 특성 및 이종 금속을 도입하여 액체 연료의 선택도를 향상시키고 메탄 생성 양을 줄

이려는 시도가 있었다. 한편으로는 값비싼 귀금속의 양을 줄임으로써 최적의 촉매를 찾기 위한 연구를 진행하였다. 본

논문에서는 이러한 hydrogenolysis 반응 및 hydrocracking 반응에서 경제성을 높이기 위하여 어떠한 시도들이 있었는지

살펴보고자 한다. 이러한 관점에서 촉매 업사이클링 공정을 통해 플라스틱 폐기물 문제를 해결할 가능성을 제시하고

자 한다.

Plastic's ease of processing drives its growing production, resulting in a surge of plastic waste. Addressing

this issue, catalytic upcycling emerges as a promising remedy. Various metals (Ru, Pt, etc.) and supports (TiO2, CeO2,

etc.) have been employed for the chemical recycling of polyolefin plastics. Strategies to enhance liquid fuel selectivity and

minimize methane include manipulating particle size, introducing heterogeneous metals, and tuning support characteristics.

Simultaneously, endeavors to optimize catalysts by reducing precious metal usage were pursued. This study explores

enhancing economic viability in hydrogenolysis and hydrocracking reactions, underscoring the potential of catalystdriven

upcycling to tackle plastic waste.
