摘要

为探究催化剂与烘焙耦合对生物质热解特性的影响,将榆木进行220、250、280 ℃温度下的烘焙,然后以煤灰、生物质灰、泥岩为催化剂,在立式炉中进行热解实验,同时利用热重分析仪（TG）研究催化剂与烘焙耦合对榆木热解失重特性和动力学特性的影响。结果表明：煤灰和生物质灰分别与烘焙耦合能促进热解气中CO₂的生成,而泥岩催化热解产氢效果显著。280 ℃下,泥岩与烘焙耦合对酚类物质的提升最明显,可达54.69%;而煤灰和生物质灰分别与烘焙耦合对芳香烃的生成更有利。3种催化剂分别与220 ℃烘焙耦合对气体产率的促进作用最明显。在低温段,泥岩会提高原样热解反应活化能,但与烘焙耦合则使热解反应活化能降低;在高温段,煤灰会降低热解反应活化能,而生物质灰和泥岩则会增加热解反应活化能。

Abstract

In order to investigate the effect of catalyst and torrefaction coupling on the pyrolysis characteristics of biomass, the elm was torrefied under the various temperatures （220, 250, and 280 ℃）, and then conducted pyrolysis experiments in a vertical furnace using coal ash, biomass ash, and mudstone as the catalysts, and meanwhile, a thermogravimetric analyzer （TG） was utilized to study the effect of catalyst and torrefaction coupling on the weight loss characteristics and kinetic properties of elmwood pyrolysis. The results show that the coupling of coal ash and biomass ash with torrefaction promotes the generation of CO₂ in the pyrolysis gas, while the effect of hydrogen production by mudstone catalyzed pyrolysis is significant. The coupling of mudstone with torrefaction enhances phenolics up to 54.69% at the torrefaction temperature of 280 ℃, while coal ash and biomass ash with torrefaction is more favorable for the generation of aromatic hydrocarbons. The three catalysts coupled respectively respectively with torrefaction at 220 ℃ showes the most obvious promotion of gas yield, respectively. In the low-temperature section, mudstone increases the pyrolysis activation energy of raw sample, but decreases the pyrolysis activation energy of torrefied samples; in the high-temperature section, coal ash decreases the pyrolysis activation energy, while biomass ash and mudstone both increases the pyrolysis activation energy respectively.
