This study was carried out to investigate pyrolysis characteristics of moso bamboo (Phyllostachys pubescens), including outer layer (OB), middle layer (MB) and inner layer (IB) and bamboo leaves (BL), through TG-FTIR and Py-GC/MS. The results showed that 70% of weight loss occurred at rapid pyrolysis stage with temperature of 200-400 °C. With increase in heating rate, pyrolysis process shifted toward higher temperature. IB, OB, MB and BL had a different activation energy at different conversion rates. BL had a higher activation energy than IB, OB and MB. The volatiles of bamboo was complicated with 2-30 of C atoms. IB, OB and MB mainly released benzofuran, hydroxyacetaldehyde and 2-Pentanone. BL released furan, acetic acid and phenol. The main pyrolysis products included HO, CH, CO, CO, carboxylic acids, NO, NO. Pyrolysis products of IB was the most and that of BL was the lowest. MB had the lowest pyrolysis temperature.
本研究通过 TG-FTIR 和 Py-GC/MS 对毛竹（Phyllostachys pubescens）的外竹层（OB）、中竹层（MB）、内竹层（IB）和竹叶（BL）的热解特性进行了研究。结果表明，在 200-400°C 的快速热解阶段，毛竹的 70%重量损失。随着升温速率的增加，热解过程向更高的温度移动。在不同的转化率下，IB、OB、MB 和 BL 具有不同的活化能。BL 的活化能高于 IB、OB 和 MB。毛竹的挥发物具有 2-30 个碳原子。IB、OB 和 MB 主要释放苯并呋喃、羟基乙醛和 2-戊酮。BL 释放呋喃、乙酸和苯酚。主要的热解产物包括 HO、CH、CO、CO、羧酸、NO、NO。IB 的热解产物最多，BL 的热解产物最少。MB 的热解温度最低。
