Abstract
The pyrolysis experiment of rice husk was conducted in a self-built fix bed heater. Two chromatographic columns,RTX-5MS and RTX-WAX,were used for the collection of mixture of pyrolytic oil and dichloromethane solution,which were later analyzed by GC-MS. Results showed that the compositions of pyrolytic oils at different final temperatures changed little. As the pyrolysis temperature rose , pyrolytic oil yield first increased and then decreased. The water phase of dichloromethane and pyrolytic oil solution contained relatively few compounds,mainly formic acid, acetic acid,and 1-hydroxy-2-propanone,while the oil phase contained complicated compounds, including furfural,furfuryl alcohol,phenols and ketones. The analysis of dichloromethane in oil phase and pyrolytic oil solution at 600℃ showed that through column RTX-5MS analysis,the first five compounds were furfural,2-butanone,acetic acid,phenol and 2-methoxy phenol,and that through RTX-WAX column analysis,the first five compounds were phenol,2-methoxy phenol,4-ethyl phenol, acetic acid and 3-methyl phenol.关键词
