Condition optimization of simulated bio-oil molecular distillation via response surface method
摘要
Abstract
Molecular distillation is an efficient bio-oil separation technology. The wiped-film molecular distillation apparatus was employed to investigate the separation properties of the simulated bio-oil under different process conditions including distillation temperatures,distillation pressures and feed rates,respectively. Then,the response surface method was used to study the effects of multi-factors on the molecular distillation. According to ANOVA analysis,the F-value of 21.25 implied the model was significant. The concentration of the acid,the aldehyde and the ketone in the light fraction was set as the response value and the optimum condition of 69.83℃,1498.31Pa and 5.54mL/min was determined. On this condition,the concentration of the acids,the aldehydes and the ketones was as high as 39.12%. Finally,the validation test of the simulated bio-oil was carried out under the optimum condition. The concentration of the target products in the light fraction of 38.96% was achieved,which was highly in accordance with the result from response surface method. The concentration of acid,the aldehyde and the ketone via molecular distillation increased from 28.50% to 38.96%,and the concentration of the phenols decreased from 37.50% to 25.14%.关键词
