A newly developed two-step catalytic pyrolysis process (TSCP) based on poly-generation technology is proposed to convert reed straw (RS) into phenol-rich bio-oil, hydrogen-rich gas, and solid carbon degradation material over iron-loaded activated carbon. The effects of the first step pyrolysis temperature (T1) and catalyst composition on the product distribution and target product selectivity were investigated. When T1 was 350 °C and 10% Fe/AC catalyst was selected, the concentration of phenolic compounds and H₂ peaked at 63.87 area% and 63.29 vol%, respectively. The iron-loaded activated carbon catalysts promoted the decarboxylation and decarbonylation reactions of cellulose and hemicellulose decomposition products, as well as the demethylation and demethoxylation reactions of lignin for the selective production of phenolic compounds and hydrogen gas. In addition, 94.7% quinclorac (10 mg/L) removal was achieved with 0.2 g/L 10% Fe/AC catalyst-doped pyrolysis carbon and 2 mM PMS within 90 min. This study could realize the high-value comprehensive utilization of reed and provide a reference for the full quantitative utilization of other agricultural and forestry wastes.

提出了一种新开发的基于多联产技术的两步催化热解工艺（TSCP），通过负载铁的活性炭将芦苇秸秆（RS）转化为富含苯酚的生物油、富氢气体和固体碳降解材料。碳。研究了第一步热解温度（T1）和催化剂组成对产物分布和目标产物选择性的影响。当T1为350℃、选择10%Fe/AC催化剂时，酚类化合物和H₂的浓度峰值分别为63.87面积%和63.29体积%。载铁活性炭催化剂促进纤维素和半纤维素的脱羧和脱羰反应分解产物，以及木质素的脱甲基和脱甲氧基反应，用于选择性生产酚类化合物和氢气。此外，使用 0.2 g/L 10% Fe/AC 催化剂掺杂的热解碳和 2 mM PMS 在 90 分钟内去除了 94.7% 二氯苯甲酸 (10 mg/L)。该研究可实现芦苇的高值化综合利用，为其他农林废弃物的充分量化利用提供参考。
