Al-MCM-48 was applied to the catalytic pyrolysis of lignin for the first time. The pyrolysis reaction and in-situ product were analyzed by pyrolysis gas chromatography/mass spectrometry. The main products of the non-catalytic pyrolysis of lignin were phenols. The use of Al-MCM-48 increased the production of light phenols considerably. The yields of high-value-added compounds, such as hydrocarbons and aromatics, were also increased by catalytic upgrading. Al-MCM-48 is believed to promote cracking, aromatization and deoxygenation, such as decarbonylation. On the other hand, Si-MCM-48, which has no acid sites, showed lower deoxygenation efficiency than Al-MCM-48. Al-MCM-48 could be regenerated by calcining in air.
Al-MCM-48首次应用于木质素的催化热解。通过热解气相色谱/质谱联用仪对热解反应和原位产物进行了分析。木质素非催化热解的主要产物是酚类。Al-MCM-48的使用显著提高了轻质酚类的产量。通过催化提质，高附加值化合物如烃类和芳烃的产率也有所提高。据信Al-MCM-48能促进裂解、芳构化和脱氧反应，如脱羰反应。另一方面，不含酸性位点的Si-MCM-48的脱氧效率低于Al-MCM-48。Al-MCM-48可以通过在空气中煅烧进行再生。
