摘要/Abstract

摘要： 以废弃生物质制备生物炭进行高值利用为目标，以废弃白菜叶(waste cabbage leave，WCL)为原料，在系列热解温度(420，520，620，720℃)下制备生物炭，利用傅里叶红外光谱仪、X射线衍射等手段对生物炭进行表征，考察热解气体与生物炭性质之间的关系.结果表明:生物质的能量回收要聚焦工艺条件，与热解气、升温速率等条件相关，而生物炭的生产则与热解终温和保持时间等相关.不同的热解气体与生物炭表面官能团变化、微观碳结构可以建立对应关系.低温生物炭表面官能团丰度较高，含氧官能团丰度可以达到55%，高温生物炭结构更有序；此外，520℃可能是WCL的生物热解特征温度点.

Abstract: The waste cabbage leave(WCL)was used as raw material to prepare biochars under various temperatures(420， 520， 620， 720℃). Biochars were comprehensively characterized by Fourier transform infrared spectroscopy(FTIR)， X-ray diffraction(XRD)and so on. Additionally， the relationship between pyrolysis gas and biochar properties was investigated. The results show that biomass energy recovery could concentrate on the process conditions， as pyrolysis gas is significantly correlated with the heating rate， while biochar production is influenced by the heat and retention time at the end of pyrolysis. Pyrolytic gases could be correlated with the changes of functional groups on biochar surface and the microstructure of carbon. High-temperature biochars have more ordered structures， but low-temperature biochars have more functional groups and their oxygen-containing functional groups can reach 55%. In addition， 520℃ may be the characteristic temperature point of bio-pyrolysis of WCL.

Key words: biochar; waste cabbage leave; TG-FTIR; isothermal pyrolysis; surface functional group
