Abstract

The escalating demand for plastic presents an immense peril to both the environment and humanity. Not only have there been notable advancements in the creation of advanced biodegradable polymers, but there has also been a lack of attention towards tackling the current issue of plastic waste. Processing fuels via plastic waste valorization provides a feasible approach to recycle plastics and mitigating pollution for the improvement of society. This review addresses a comprehensive analysis of various heterogeneous catalysts in the context of plastic pyrolysis to produce fuel, intending to identify an eco-friendly method for recycling garbage. The choice of catalyst has a substantial effect on the disintegration process of waste plastic, dictating the properties of the resulting fuel, encompassing both the amount and the quality. Pyrolysis, an alternative method for addressing the increasing waste disposal issue, is a non-toxic process that does not release hazardous pollutants, in contrast to incineration. The waste plastic serves as a feedstock for pyrolysis process, employing innovative, environmentally friendly catalysts derived from natural and other sources, to generate fuel oil that possesses similar physical characteristics to the diminishing petroleum-based fuels. This critical review analyzes the impact of different heterogeneous catalysts on the process of transforming waste plastic to produce fuel through pyrolysis. Heterogeneous catalysts are crucial to the process of turning discarded plastics into oil, offering significant potential for improving not only economic and environmental conditions but also benefiting both industry and society.

对异相催化剂的严格审查:利用废塑料热解制造燃料
对塑料不断增长的需求给环境和人类都带来了巨大的危险。不仅在制造先进的可生物降解聚合物方面取得了显著进展,而且在解决当前的塑料废物问题方面也缺乏关注。通过塑料废弃物的价值化来加工燃料,为回收利用塑料和减轻污染以改善社会提供了一种可行的方法。本综述全面分析了塑料热解生产燃料过程中的各种异相催化剂,旨在找出一种环保的垃圾回收方法。催化剂的选择对废塑料的分解过程有很大影响,决定了所产生燃料的性质,包括数量和质量。热解是解决日益严重的垃圾处理问题的另一种方法,与焚烧相比,热解过程无毒,不会释放有害污染物。废塑料可作为热解过程的原料,利用从天然和其他来源提取的创新型环保催化剂,生成与日益减少的石油基燃料具有相似物理特性的燃料油。这篇评论分析了不同的异相催化剂对通过热解将废塑料转化为燃料的过程的影响。异相催化剂对于将废弃塑料转化为石油的过程至关重要,不仅在改善经济和环境条件方面具有巨大潜力,而且还能造福于工业和社会。

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
