汽车粉碎机残渣(ASR)热解产生固体、液体和气体产物，特别是热解石油和天然气，可作为可再生的替代能源。由于一次热解反应不完全，气态产物产率较低。热解焦油在冷凝成液体之前含有化学上不稳定的挥发物。了解挥发性产品的特性将有助于后续工艺的设计和改进。为了准确分析ASR一次热解挥发产物的化学性质和产率，采用了TG-FTIR-GC/MS分析技术。根据混合型ASR、ASR及其主要组分的Gram-Schmidt图谱、3D堆积图和GC/MS图谱的分析结果，ASR的主要热解产物是烷烃、烯烃和醇，在1900-1400 cm−1的波数范围内都有密集和难以区分的弱峰。这些产物中有许多化学键不稳定或较弱，如=CH-，=CH2，-C=C-，和-C=CH2。因此，通过进一步的催化热解气化、水蒸气气化或更高温度的热解，可以获得更多热值更高的合成气。
Automobile shredder residue (ASR) pyrolysis produces solid, liquid, and gaseous products, particularly pyrolysis oil and gas, which could be used as renewable alternative energy resources. Due to the primary pyrolysis reaction not being complete, the yield of gaseous product is low. The pyrolysis tar comprises chemically unstable volatiles before condensing into liquid. Understanding the characteristics of volatile products will aid the design and improvement of subsequent processes. In order to accurately analyze the chemical characteristics and yields of volatile products of ASR primary pyrolysis, TG–FTIR–GC/MS analysis technology was used. According to the analysis results of the Gram–Schmidt profiles, the 3D stack plots, and GC/MS chromatograms of MixASR, ASR, and its main components, the major pyrolytic products of ASR included alkanes, olefins, and alcohols, and both had dense and indistinguishable weak peaks in the wavenumber range of 1900–1400 cm−1. Many of these products have unstable or weaker chemical bonds, such as =CH–, =CH2, –C=C–, and –C=CH2. Hence, more syngas with higher heating values can be obtained with further catalytic pyrolysis gasification, steam gasification, or higher temperature pyrolysis.
