Abstract

The objective of this study was to investigate the catalytic effect of sodium carbonate on tire pyrolysis oil (TPO) yield and composition when increasing the concentration of a catalyst in the feed material. The collected tire pyrolysis oil samples were analyzed using Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS) and compared to diesel fuel. When the catalyst was introduced, the yield increased from 35 percent to 43 percent for the 10 percent catalyst. It was found from FTIR and GC-MS analyses that the TPO samples produced by both catalytic and thermal pyrolysis were complex mixtures of aliphatic, aromatic, nitrogen, and oxygen-containing compounds with carbon content ranging between C₄ and C₄₅ and there was an increase in branching with an increase in the catalyst. The TPO was found to contain aliphatic compounds that were similar to the ones contained in diesel fuel, indicating that the TPO contained some diesel.

摘要

本研究的目的是研究当增加进料中催化剂的浓度时，碳酸钠对轮胎热解油 (TPO) 产率和组成的催化作用。使用傅里叶变换红外光谱 (FTIR) 和气相色谱-质谱 (GC-MS) 分析收集的轮胎热解油样品，并与柴油燃料进行比较。引入催化剂后，10% 催化剂的产率从 35% 增加到 43%。通过FTIR和GC-MS分析发现，催化和热裂解产生的TPO样品是脂肪族、芳香族、含氮和含氧化合物的复杂混合物，碳含量介于C 4 和_C 45_之间并且随着催化剂的增加，支化增加。发现 TPO 含有类似于柴油中所含脂肪族化合物，表明 TPO 含有一些柴油。
