摘要

提出了一种创新的循环原位共热解工艺，用于协同处理凤凰树叶（PTL）和纯化对苯二甲酸污泥灰（PTASA）。系统研究了循环共热解对三相产物演化、焦油组成和生物炭稳定性的影响，并阐明了其协同作用机制。结果表明，在第四轮循环共热解过程中，综合热解指数（CPI）值提高了261%。同时，PTASA的加入使合成气收率提高到69.77%，促进了焦油的裂解，使焦油收率降至1.98%，因为10个以上碳原子的焦油组分被进一步分解。在共热解过程中，Mn和Ca元素主要以（CaO）0.9(MnO)0.1的稳定形态存在，而Co元素则由于碳的还原和富氧PTL中含氧化合物的氧化作用，以金属（Co）和氧化物（CoO）形态存在。值得注意的是，第5轮循环共热解生成的生物炭H/C和O/C值最低，热稳定性最高。

Cyclic in-situ co-pyrolysis of Phoenix Tree's Leaves and Purified Terephthalic Acid Sludge Ash based biochar for producing high-quality syngas

An innovative cyclic in-situ co-pyrolysis process was proposed for the synergistic treatment of Phoenix Tree Leaves (PTL) and Purified Terephthalic Acid Sludge Ash (PTASA). The influence of cyclic co-pyrolysis on the evolution of three-phase products, tar composition, and biochar stability was systematically investigated, and the underlying synergistic mechanism was elucidated. Results indicated that the Comprehensive pyrolysis index (CPI) value increased by 261 % in the fourth round of cyclic co-pyrolysis. Meanwhile, the addition of PTASA enhanced the yield of syngas to 69.77 %, and facilitated the tar cracking, reducing the tar yield to 1.98 %, as the tar components more than 10 carbon atoms were further decomposed. In the co-pyrolysis process, the elements Mn and Ca mainly existed in the stable form of (CaO)_0.9(MnO)_0.1, while Co existed in the metallic (Co) and oxide (CoO) forms due to the reduction by carbon and the oxidation by oxygenated compounds in oxygen-rich PTL. Notably, the biochar derived from the fifth round of cyclic co-pyrolysis exhibited the lowest H/C and O/C values, indicating the highest thermal stability.
