摘    要:利用热重红外联用技术在线分析研究了白松在不同升温速率下的热裂解行为,结果表明木材的热裂解可归结于纤维素、半纤维素和木质素三种主要组分的热裂解。白松的热裂解产物主要有酸类、醇类、醛类、酮类、酯类、水分和小分子气体等。在线红外分析结果表明白松热裂解过程中先析出游离水,随后发生解聚和脱水反应,主要的苷键和碳碳键断开形成各种烃类、醇类、醛类和酸类等物质,随后,这些大分子物质又二次降解为一氧化碳为主的气体产物。

关 键 词:生物质  热裂解  热重-傅里叶红外联用分析

Abstract:The pyrolysis behavior of white pine was studied at different heating rates by thermogravimetric (TG) analysis coupled with Fourier Transform Infrared Spectroscopy (FTIR). Experimental results showed that the pyrolysis of wood can be considered as the pyrolysis of the combination of three main components, i.e. cellulose, hemicellulose and lignin. The product was mainly consisted of acids, alcohols, aldehydes, ketones, esters, water and small-molecule gases. The online FTIR analysis showed that free water released out firstly during white pine pyrolysis, followed by the depolymerization and dehydration. Glucosidic bond and carbon-carbon bond broke into the formation of a series of hydrocarbons, alcohols, aldehydes, acids, and etc. Subsequently these large-molecule compounds decomposed further into gases, such as carbon monoxide.
Keywords:biomass: Dvrolvsis: TG-FTIR analvsis
