| 摘 要： | 精馏生物柴油的副产物可得到黄色的粗甘油产品。利用椰壳活性炭对粗甘油产品进行脱色过程研究,确定LY-725B型活性炭为最佳脱色剂。其次,选择脱色温度、脱色时间和活性炭用量为响应面优化实验的3个显著因素,利用Minitab软件对粗甘油的脱色过程进行了优化,得到了最佳工艺条件:m(活性炭)/m(粗甘油)=0.022,脱色温度48℃,脱色时间31 min,此时甘油透光率达96.1%,甘油单程回收率为72.6%。

| Abstract: | Crude glycerol can be obtained with the distillation of biodiesel by-product.Its decoloration process by the absorption of active carbon prepared by coconut shell was investigated and analyzed.The results indicated that LY-725B active carbon was selected as the optimal decolorant.In addition,the decoloration temperature,the decoloration time and the active carbon dosage were chosen as the three main factors of the response surface optimization model.After experiment and analysis with the Minitab Program,the... |
