摘　　要：通过热解将固体燃料在热化学上转化为运输燃料和增值化学品是实现固体燃料高效利用的最为切实可行和兼顾经济性的途径之一。由于热解反应产物的复杂性,对固体燃料热解的中间产物和最终产物在分子水平上进行全面阐明对于理解热解反应机理至关重要,同时对提高热解过程的可持续性具有积极意义。光电离质谱(PIMS)技术被普遍认为是一种高度通用的过程分析技术,通过对热解气相产物中的离子进行实时检测和分析,为热解提供了实时的信息。为此,本工作综述了近年来PIMS技术在固体燃料(包括煤、生物质和固体推进剂)热解领域的应用,并对不同实验和模型的进展进行了概述。这些进展相互促进,有助于学者加深对热解固体燃料复杂过程的理解,并为未来深入研究热解机理提供有力支持。Pyrolysis,an economically viable method,thermochemically converts solid fuel into transportation fuels and value-added chemicals,such as clean gas,liquid fuels,and chemicals,alongside undesirable by-products.Photoionization mass spectrometry(PIMS)is a versatile technique for real-time process analysis,offering‘soft’ionization for complex analytes,detecting and analyzing ions during in-situ pyrolysis.This review focuses on recent applications of PIMS during pyrolysis of solid fuels(i.e.coal,biomass and energetic materials).It summarizes studies on mass spectrometric analysis combined with different reactors and highlights the benefits through online PIMS as a diagnostic tool for in-situ analysis.It provides an overview of interplay between experimental advancements and models and discusses future perspectives,potential applications in support of mechanistic studies.
