摘要： 利用JHP-5型居里点裂解仪,在358、5、590和670℃ 4种居里点温度下快速热裂解竹材,通过GC-MS在线分析裂解产物.结果表明竹材居里点裂解液相主要产物为糠醛和酚类物质,其中445℃时2,3-二氢苯并呋喃的相对含量多达21%,并且液相主要产物的相对含量随温度的提高呈现先增后减的变化规律,裂解温度为445～590℃更利于液相产物的生成.裂解机理分析得知糠醛是由纤维素和半纤维素裂解产生,而酚类物质则来源于木质素.

Abstract: Bamboo is pyrolyzed at 358,445,590 and 670℃ in JHP-5 model Curie-point pyrolysis. The results of GC-MS on-line analysis show that the main liquid products are furfural and aromatic substances. The relative content of 2,3-dihydrobenzofuran comes up to 21% at 445℃, and the relative contents of main liquid products climb up then decline as the pyrolysis temperature increasing. The temperature between 445℃ to 590℃ is fit for liquid products in this experimental condition. Pyrolysis mechanism indicates that furfural and aromatic substances are formed from the pyrolysis of cellulose, hemicellulose and lignin, respectively.

Key words: Curie-point pyrolysis, bamboo
