竹材居里点快速热裂解研究

Abstract

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
