Abstract

The management of waste plastics poses a significant challenge due to their inherent chemical stability, large-scale production, and short service life. As plastics are primarily composed of carbon and hydrogen, there is growing interest in the high-value conversion of plastic waste for the targeted production of hydrogen. However, the thermodynamic constraints of the processes, along with the associated challenges in hydrogen storage and transportation, limit the practical application of hydrogen production technologies derived from plastic waste. Consequently, in situ utilization of hydrogen generated from plastic waste has emerged as a promising strategy. This perspective elucidates the fundamental principles of in situ hydrogen utilization and establishes a theoretical framework for evaluating existing studies and guiding future research. Based on this framework, we systematically assess the latest advancements, critically addressing the challenges encountered and proposing directions for future research. The objective of this paper is to provide a comprehensive roadmap for the efficient utilization of hydrogen energy derived from plastic waste, thereby facilitating the establishment of a hydrogen circular economy.

氢在塑料废弃物回收和升级利用中的原位利用

废旧塑料由于其固有的化学稳定性、生产规模大、使用寿命短等特点，对废旧塑料的管理提出了重大挑战。由于塑料主要由碳和氢组成，人们对塑料废物的高价值转化越来越感兴趣，以便有针对性地生产氢。然而，这些过程的热力学限制，以及氢储存和运输方面的相关挑战，限制了塑料废物制氢技术的实际应用。因此，就地利用塑料废物产生的氢已成为一种有前途的战略。这一视角阐明了原位氢利用的基本原理，并为评价现有研究和指导未来研究建立了理论框架。基于这个框架，我们系统地评估了最新的进展，批判性地解决了遇到的挑战，并为未来的研究提出了方向。本文的目的是为高效利用塑料废物中提取的氢能提供一个全面的路线图，从而促进氢循环经济的建立。
