摘要

塑料垃圾仍然是一个紧迫的环境问题，传统的回收方法效率不高。水热液化（HTL）和水热气化（HTG）作为创新方法出现，将聚乙烯（PE）、聚丙烯（PP）等塑料和混合城市垃圾转化为有价值的产品，如生物原油和合成气。这些工艺在亚临界水条件（300-350°C）或超临界水条件（400-450°C）下运行，为废物管理提供了多种解决方案。这篇综述综合了从1998年到2024年的250篇scopus索引文章的发现，追踪了从单聚合物研究到复杂的现实世界废物流调查的研究演变。尽管取得了进展，但挑战依然存在，包括对反应动力学的理解差距和工业可扩展性的障碍。克服这些障碍对于将热液技术纳入循环经济、实现有效的资源回收和减少污染至关重要。本文提供了详细的文献计量分析和文献综述，强调了水热方法对可持续塑料废物管理的承诺。

Valorization of plastic waste via hydrothermal liquefaction and hydrothermal gasification: Review and bibliometric analysis

Plastic waste remains a pressing environmental issue, with conventional recycling methods falling short in efficiency. Hydrothermal liquefaction (HTL) and hydrothermal gasification (HTG) emerge as innovative approaches, transforming plastics like polyethylene (PE), polypropylene (PP), and mixed municipal waste into valuable outputs such as bio-crude oil and syngas. These processes operate under subcritical water conditions (300–350°C) or supercritical water conditions (400–450°C), offering versatile solutions for waste management. This review synthesizes findings from 250 Scopus-indexed articles spanning 1998–2024, tracing the evolution of research from single-polymer studies to investigations of complex, real-world waste streams. Despite progress, challenges remain, including gaps in understanding reaction kinetics and barriers to industrial scalability. Overcoming these hurdles is essential for embedding hydrothermal technologies within the circular economy, enabling efficient resource recovery and pollution reduction. This article delivers a detailed bibliometric analysis and literature review, underscoring the promise of hydrothermal methods for sustainable plastic waste management.

期刊介绍： The Journal of Analytical and Applied Pyrolysis (JAAP) is devoted to the publication of papers dealing with innovative applications of pyrolysis processes, the characterization of products related to pyrolysis reactions, and investigations of reaction mechanism. To be considered by JAAP, a manuscript should present significant progress in these topics. The novelty must be satisfactorily argued in the cover letter. A manuscript with a cover letter to the editor not addressing the novelty is likely to be rejected without review.
