Abstract
The pyrolysis characteristics of sugarcane bagasse hemicellulose were investigated using a tubular furnace. The total gas yield and the releasing behavior of the main gas products were measured by GC analysis. The liquid products were analyzed by GC-MS and ion chromatography. The chars were investigated by elemental analysis and proximate analysis. The volatile remaining in the char extracted by isopropanol was observed by GC-MS analysis. The main gas products from hemicellulose mainly consisted of H , CO , CO, 2 2 CH . It was observed that the yield of CO and CO was higher at lower temperatures, such as 550 °C, as well 4 2 as that of H and CH at higher temperatures. The liquid products mainly contained furfural, cyclopentene-1 2 4 (2-methyl-2-cyclopentene-1, 2-cyclopentene-1, 3-methyl-2-cyclopentene), alcohols (1-butanol), organic acids (acetic acid, 4-hydroxy-butanoic acid, propanoic acid), aromatic series (phenol, ethylbenzene), besides some amounts of sugars. The products remaining in the char were mainly alcohols, cyclopentenes and complex aromatic char.
