Aromatic amines could be produced from organic wastes via catalytic pyrolysis with ammonia that served not only as a carrier gas but also as a reactant. Aromatic amines of 14.2 C% with selectivity of 57.6% were obtained from phenol-formaldehyde resins via pyrolysis over commercial HZSM-5-3 zeolite (Si/Al ratio of 80) catalyst at 650 °C. Significant synergetic effects have been observed when lignin was added, which improved aromatic amines yield by 32.2% to 11.8 C% at the mixing weight ratio of lignin to PF resins of 1:1. HZSM-5-3 was slightly deactivated after 3 cycles with acid sites loss. Catalytic co-pyrolysis of plastics and biomass wastes is a fast and effective method to produce aromatic amines.
芳香胺可以通过催化热解与氨从有机废物中产生，氨不仅可用作载气，还可用作反应物。在 650°C 下，通过商业 HZSM-5-3 沸石（Si/Al 比为 80）催化剂对酚醛树脂进行热解，可得到 14.2%C%的选择性为 57.6%的芳香胺。当添加木质素时，观察到显著的协同效应，将木质素与 PF 树脂的混合重量比为 1:1 时，芳香胺的产率提高了 32.2%，达到 11.8%C%。HZSM-5-3 在 3 个循环后略有失活，酸位损失。塑料和生物质废物的共热解是一种快速有效的生产芳香胺的方法。
