基于PY-GC/MS的生物质组分间相互作用的热解实验
The interactions among the pyrolysis of biomass components based on the PY-GC/MS
摘要
Abstract
An analytical pyrolyzer coupled with gas chromatography/mass spectrometry (PY−GC/MS) had been proposed to investigate the interactions among the pyrolysis of biomass components. Pyrolysis experiments of cellulose,xylan(molding compound of hemicellulose),lignin,and two-component mixing components were carried out. Results showed that the primary pyrolysis product of cellulose at 600℃ and 10s was laevoglucose. The primary pyrolysis products of xylan were furfural and acetic acid,while that of lignin were phenols. In addition,the cellulose promoted the pyrolysis of xylan to yeild more acetic acid and furfural. The xylan and lignin strongly inhibited the production of levoglucose from cellulose pyrolysis. The presence of cellulose and xylan strongly contributed to the generation of phenols from lignin pyrolysis,whille lignin inhibited the pyrolysis of xylan to produce acetic acid and furfural. Experiments also discovered that the interactions among the mixing components were affected by temperature and residence time.关键词
