Analysis on Pyrolysis Products of Phyllostachys heterocycla in Heat Charring

摘要

Phyllostachys heterocycla begins to be used for black bamboo with high added value. However, the pyrolysis products were severely wasted. Therefore, the chemical components from Phyllostachys heterocycla were identified by TD-GC/MS after concentration. The main constituents of 150°C volatiles were acetic acid(46.75%), carbon disulfide(4.90%), 2-furanmethanol(4.10%), benzofuran, 2,3-dihydro-(3.63%), formic acid(3.27%), 2-propanone, 1-hydroxy-(2.80%), 2-propenoic acid, 2-hydroxyethyl ester(2.64%), dimethyl ether (2.15%),. beta.-pinene(1.84%), camphor(1.71%), etc. The main constituents of 180°C volatiles were acetic acid(20.66%), benzofuran, 2,3-dihydro-(14.49%), furfural(8.86%), formic acid(8.37%), 2-furanmethanol(4.17%), 4h-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-(3.74%), 2(5h)-furanone(2.83%), 2-propanone, 1-hydroxy-(2.74%), etc. The main components of pyrolysis products of Phyllostachys heterocycla in heat charring could also be used as bioenergy materials, but were not only abundant and healthy to human.
