Abstract

This study examined the thermal and catalytic pyrolysis of waste Root (AR) using pyrolyzer-gas chromatography/mass spectrometry (Py-GC/MS). The non-catalytic pyrolysis of waste AR produced various kinds of oxygenates, such as acetic acid, hydroxy propanone, furfural, phenol, cresol, guaiacols, syringols, and so on. By applying nanoporous Al-MCM-41 with acidic properties and mesopores to the pyrolysis of waste AR, the levels of furan and aromatic hydrocarbons production increased with a concomitant decrease in the other oxygenates. The formation efficiency of furans was improved further by increasing the amount of Al-MCM-41 applied to the catalytic pyrolysis of waste AR.

摘要

本研究使用热解仪-气相色谱/质谱联用仪（Py-GC/MS）对废根（AR）进行了热解和催化热解研究。废 AR 的无催化热解产生了各种含氧物，如乙酸、羟基丙酮、糠醛、苯酚、甲酚、愈创木酚、丁香酚等。通过将具有酸性和中孔的纳米多孔 Al-MCM-41 应用于废 AR 的热解，呋喃和芳烃的产量增加，而其他含氧物的产量减少。通过增加应用于废 AR 催化热解的 Al-MCM-41 的量，呋喃的生成效率进一步提高。
