Liquefaction of Bamboo Powder in Ethanol-phenol under High Pressure and Product Characterization
摘要
Abstract
The liquefaction of bamboo powder was investigated in ethanol-phenol under high pressure using H2 SO4 as catalyst. The liquefaction conditions were optimized by response surface analysis and its result was analyzed using Design-Expert 8. 0. 6 software. The effects conditions were investigated by a five level three-factor Box-Behnken design. The results showed that the liquefaction rate reached 98. 5% under the optimum conditions, i. e. , mass ratio of phenol and bamboo powder 1∶1, ethanol and bamboo powder 18∶1, sulfuric acid amount 5%,reaction temperature 200 ℃ and reaction time 70 min. The product analysis showed that the bamboo powder could be effectively degraded in blended solvents. The FT-IR, SEM and TG results of residue indicated that the molecular structure of bamboo powder present significant change via liquefaction and the compounds with different substituent on aromatic ring were obtained. The GC-MS analysis showed that the oil produced by this way was complex in composition with some major compounds such as alcohols, phenols, ketones and esters, and the GC content of ethyl levulinate reached 10. 11%.关键词
