Chuan Ma 교수의 연구실은 플라스틱 폐기물의 자원화를 핵심 목표로 하며, 특히 할로겐을 포함한 고도로 복잡한 플라스틱 폐기물의 열분해 및 화학적 재활용 기술을 연구하고 있습니다. 주요 연구 방향은 파이로리시스를 통한 BTX(벤젠, 톨루엔, 크세놀) 및 고부가가치 화학물질 생산, 할로겐 회수, 그리고 코파이로리시스를 통한 폐자원의 효율적 활용입니다. 다양한 촉매(예: 계층적 ZSM-5, 흑연 등)와 분석 기법(열중량 분석, ESR, GC/MS 등)을 융합하여 플라스틱 폐기물의 열분해 메커니즘을 규명하고 있습니다.

Plastic waste has emerged as a serious issue due to its impact on environmental degradation and resource scarcity. Plastic recycling, especially of halogen-containing plastics, presents challenges due to potential secondary pollution and lower-value implementations. Chemical recycling via pyrolysis is the most versatile and robust approach for combating plastic waste. In this Review, we present recent advancements in halogen-plastic pyrolysis for resource utilization and the potential pathways f
Three zeolite materials (HY, Hβ, and HZSM-5) and two mesoporous solids (all-silica MCM-41 and active Al2O3) with different textural properties were investigated for their catalytic effects on the pyrolysis of brominated acrylonitrile–butadiene–styrene (Br-ABS). The results indicated that, in the absence of a catalyst, the maximum liquid yield was obtained from the pyrolysis of Br-ABS, including oil and wax. The addition of HY and Hβ zeolites significantly decreased the oil yield from 63.6 to 45
