The production of energy from wood biomass is as old as humanity itself. There has been enormous progress in research of sustainable pyrolysis processes for optimal energy conversion in the past 30 years. Pyrolisis–gas chromatography–mass spectrometry (PY‐GC‐MS) was used to examine the components of bark and wood of Toona sinensis for expanding high value utilization different parts of trees. In the study, 174 chemical constituents were identified in the bark; 169 chemical constituents were identified in the wood, respectively. The chemical composition of bark is different from that of wood. The change in thermal cracking 30 min ago is not very large. In the retention time is more than 30 min, they are very different. Because the ash content of bark had much large corresponding wood. Mainly the phenols and their derivatives formed after the pyrolysis of lignin and extractives. The chemical composition of T. sinensis provides a scientific basis for the development and utilization of the plant. The richer chemical constituents of T. sinensis are found, which will provide new scientific evidence for further development and utilization of bark and wood of T. sinensis.

热解-气相色谱-质谱法分析香椿树皮和木材的化学成分

木材生物质能产生的能量与人类本身一样古老。在过去的30年中，在可持续热解过程中实现最佳能量转化的研究取得了巨大进展。用热解-气相色谱-质谱法（PY-GC-MS）检测香椿树皮和木材的成分扩大树木不同部位的高价值利用。在这项研究中，树皮中发现了174种化学成分。木材中分别鉴定出169种化学成分。树皮的化学成分与木材不同。30分钟前的热裂解变化不是很大。在保留时间超过30分钟时，它们有很大不同。因为树皮的灰分含大量相应的木材。主要是木质素和提取物热解后形成的酚及其衍生物。中华绒螯蟹的化学成分为植物的开发利用提供了科学依据。中华绒螯蟹中较丰富的化学成分被发现，这将为进一步开发和利用中华绒螯蟹的树皮和木材提供新的科学依据。
