摘　　要：In recent years, great attention has been paid to the exploitation and use of biomass energy.Using bamboo as the raw material to produce energy and other chemicals is significantly important.A primary study was made on the pubescens,one kind of bamboo distributed broadly in China with fast growth rate.The contents of cellulose, hemi-cellulose, and lignin in different parts of pubescens with different growth ages, as major components of the cell wall,were determined.The analysis procedures were as follows:firstly the substances other than the above mentioned three were removed chemically, then the hydrolyzed cellulose liquid was oxidized with excess oxidants,and at last titrated.Pubescens powder was packed into the quartz tube reactor, then was heated from room temperature to 300,350, 400, 450, 500, 550 ℃ and 600 ℃ respectively in flowing N 2.Pyrolysis was held at the final temperature for 10 h.The liquid products were analyzed with GC/MS.The main products in the liquid obtained were: acetic acid, 2,6-dimethoxy phenol, 2,3-dihydrobenzofuran,etc.The pyrolysis temperature exerted great effect on the composition of the liquid products.The distribution of the products could be regulated by controlling pyrolysis temperature.
